On-board information and measuring complexes and registration systems are intended to control the parameters of both systems and components of the prototype and the sample of automotive and armored vehicles in general to obtain qualitative and quantitative characteristics to assess their compliance with specifications of technical development requirements. At present stage, there is often a need to improve methods for optimizing the development of on-board systems for collecting and processing information to ensure conducting of testing works, which take into account particulars of the electronic equipment development and are based on a unified approach to the optimal use of resources of collection and information processing systems. Analysis of the problem of rational use of resources of standard means of measurement, registration and indication in the system of onboard measurements and further processing of the results in automated systems for collecting and processing information for their use in testing mass produced (modernized) aircraft was previously considered by Soviet, Ukrainian and foreign scientists. But they do not give a complete picture of the algorithm, completeness and quality of tests using standard measuring instruments installed on board aircraft and do not answer a number of questions related to the optimization of the computational process. In particular, the potentials of standard means of measurement, registration and indication as part of the on- board measurement system for testing mass produced (modernized) aircraft and installed components, units and systems under test are not fully explored. The issue of building optimal data collection programs that implement the inquiry of measuring channels with restrictions on the frequency of channel inquiry and information processing speed is insufficiently studied. The novelty of the research consists in the developing of an algorithm for capabilities analysis and procedure for incorporating standard measuring, registration and indication instruments in the on-board measuring system within a single measuring and information field for testing mass produced (modernized) samples of weapons. Approbation and implementation of the abovementioned algorithms will allow test teams to minimize time spent on the development (selection) of the onboard measurement system to ensure research and testing of both modernized aircraft, vehicles and armored vehicles and newly created with advanced information systems.

A dynamic calibration method based on elliptical standard was put forward to further improve the calibration repeatability of measurement system of form measuring instruments. In this method, the radius difference of the major axis to the minor axis of elliptic contour acts as the standard value to calibrate the measuring system, and a low pass filter is used to filter the roughness, electrical noise and high frequency vibration signal which mixed into measurement data, the elliptic contour feature can be obtained accurately based on the low order harmonic properties. Compared with the traditional calibration method of flick standard, the proposed method ensure the calibration state is well consistent with the normal measuring state of the measuring system. Experimental results indicate that the calibration repeatability with 10nm can be achieved by measuring an elliptical standard. This method has been used in the calibration of measurement system of self-made ultra-precision cylindricity measuring instrument.

On-board information measurement and recording systems are designed to control the parameters of both systems and units of the prototype and the sample of automotive equipment and armored vehicles in general, to obtain qualitative and quantitative characteristics to assess their compliance with technical requirements of the request for proposal. The universal modular type on-board information-measuring system must provide acquisition, conversion and registration on the on-board drive of parametric (analog and digital), discrete, audio and video information from on- board systems of armament and military equipment (AME) sample during tests. A special place is occupied by data collection and processing systems during automotive equipment and armored vehicles tests. This is due to the need to obtain during experiments quantitative information about the characteristics of the sample and its systems on the basis of an unbiased evaluation of a significant number of values of physical quantities, which are determined experimentally. Despite the significant difference in the technical characteristics and methods of application of different types of armored vehicles, the information support of their tests has lots in common. From the technical point of view, tests of armored vehicles are a process of obtaining, converting, registering and processing of measuring information generated by on-board systems of AME test sample. The whole complex of engineering measurements instruments (ground measuring instruments, on-board measuring systems, trajectory measurement systems, telemetry systems) using common time equipment, means of acquisition and processing measuring information, control and communication is combined into a single information measuring and computing complex, which in turn allows giving an unbiased evaluation of the characteristics and features of the test object as a whole. In order to improve the quality of testing of new and upgraded sample of automotive equipment and armored vehicles, the need for a universal on-board information measurement and recording systems, its characteristics are analysed, proposals for the composition, as well as general requirements were introduced.

Measurement System Analysis (MSA) comprises a set of methods aiming to identify and assess variation of measurement results that can be assigned to a measurement system (gauge, personnel, procedure, standard, ambient conditions, etc.). It became a requirement of quality management systems in automotive industry, according to ISO/TS 16949. Moreover, most of automotive suppliers have to meet OEMs requirements specified in APQP (Advanced Product Quality Planning), PPAP (Production Part Approval Process) and MSA manuals. Many other industries adopted the same approach, expecting their suppliers to perform MSA in compliance with the above guidelines. The basic requirement regarding MSA scope is that it should be carried out for all measuring instruments referred to in Control Plans. Among methods available, gauge R&R seems to be the most popular method of measuring system capability assessment. However, although the assessment has to be performed periodically, none of the above mentioned guidelines suggest any method for MSA planning. The paper describes a few propositions on how the problem can be practically resolved basing on a risk associated with each measurement system. The first proposed method is based on simple risk analysis, which can be easily run together with developing a Control Plan. It uses process capability index (required or achieved) and characteristics impact on product/process function for making a decision on MSA frequency and scope. The variant of the method uses gauge robustness assessment as another risk factor.The other proposition assumes that a process FMEA (Failure Mode and Effects Analysis) is developed. The method uses performed FMEA to establish priorities for MSA. Basing on the priorities, frequency and scope of MSA can be planned.

The approach to creating standard means for reproducing units of volumetric activity of radon and thoron and flux density of radon from the soil surface is described based on the physical principles of reproducing these units of quantities and using as technical means for reproducing bubblers with a radioactive solution of radium salt, reference capacities of known volume, emanation chambers for generation of a toron, a gamma spectrometer with a semiconductor detector from highly pure germanium and radon radiometers. Reproduction consists in the physical realization of units in accordance with their definition as applied to the formation of radon and thoron in the radioactive rows of radium and thorium. The proposed approach will allow to determine the structural, structural and other technical solutions of standard measuring instruments, as well as specific techniques and methods of working with them. The creation of standard tools and technologies for reproducing units of volumetric activity of radon and thoron and the density of radon flux from the soil surface will ensure the unity and reliability of measurements in the field of ionizing radiation, traceability of units and bringing the characteristics of national standards in line with world achievements.

The Impact

Digital technologies are no longer the future but are the present of civil proceedings. That is why any research in this direction seems to be relevant. At the same time, some of the fundamental problems remain unattended by the scientific community. One of these problems is the problem of classification of digital technologies in civil proceedings. On the basis of instrumental and genetic approaches to the understanding of digital technologies, it is concluded that their most significant feature is the ability to mediate the interaction of participants in legal proceedings with information; their differentiating feature is the function performed by a particular technology in the interaction with information. On this basis, it is proposed to distinguish the following groups of digital technologies in civil proceedings: a) technologies of recording, storing and displaying (reproducing) information, b) technologies of transferring information, c) technologies of processing information. A brief description is given to each of the groups. Presented classification could serve as a basis for a more systematic discussion of the impact of digital technologies on the essence of civil proceedings. Particularly, it is pointed out that issues of recording, storing, reproducing and transferring information are traditionally more «technological» for civil process, while issues of information processing are more conceptual.

Accuracy And Repeatability

The article discusses the quality testing of a measuring system consisting of a CNC machine with measuring probes. The research was conducted in a broader context regarding the implementation of the closed door technology, i.e., production without human intervention, in an aviation plant manufacturing aircraft gearbox systems. This technology may involve automated measuring operations performed in machining centers, and not in measuring laboratories, provided that the quality of the measurements is appropriate. The aim of the study was to investigate whether the CNC machining device can be used to measure the geometric features of aircraft gearbox housing. For this purpose, measurement experiments were carried out with the use of three different probes. Measurements were carried out using four sequences of increasing complexity, so that, after error analysis, it was possible to find the causes of possible irregularities. A reference ring with known dimensions and position in the working space of the machine was used for the measurements performed as part of the assessment of the measurement system. The quality of the measurements was evaluated with the use of repeatability and reproducibility testing and statistical process control. The analysis results showed that the tested measurement system ensures adequate accuracy and repeatability, and the measurement process is characterized with adequate efficiency in relation to the manufacturing tolerance of the components produced using the machine. Thus, it was proven that the measurement process can be carried out on a machining device, which enables its integration into the closed door technology.

Gas Solubilities

Efficient and environmentally responsible use of resources requires the development and optimization of gas separation processes. A promising approach is the use of liquids that are designed for specific tasks, e.g., the capture of carbon dioxide or other greenhouse gases. This requires an accurate determination of gas solubilities for a broad range of temperatures and pressures. However, state of the art measurement techniques are often very time consuming or exhibit other pitfalls that prevent their use as efficient screening tools. Here, we show that the application of Raman spectroscopy through a compact measuring system can simplify data acquisition for the determination of gas solubilities in liquids. To demonstrate that this approach is expedient, we determined gas solubilities of carbon dioxide in water for three isotherms T = (288.15, 293.15, 298.15) K over a pressure range from p = (0.5–5) MPa and in three imidazolium-based ionic liquids for one isotherm T = 298.15 K at pressures from p = (0.1–5) MPa. When compared to data in the literature, all results are within the reported uncertainties of the measurement techniques involved. The developed analysis method eliminates the need for a lengthy volume or mass calibration of the sample prior to the measurements and, therefore, allows for fast screening of samples, which can help to advance gas separation processes in scientific and industrial applications.

In pursuit of improved safety, Norfolk Southern Corp. (NS) has partnered with Amberg Technologies to explore the potential benefits of a laser-based measurement system for measuring over dimensional freight rail shipments. Shipments that do not fall within a standard geometric envelope, denoted as Plate B in the Association of American Railroads (AAR) Open Top Loading Rules [1], are considered to be over dimensional, or High-Wide Loads (HWLs). Extending beyond the limits of the Plate B diagram, these loads are not permitted in unrestricted interchange service. Instead, they must be measured both at points of origin and at interchange points. For US Class I Railroads, the de facto method for measuring HWLs requires mechanical personnel to either climb on the equipment or use a ladder and physically measure the overall height and width of the load. Using a tape measure, plumb line, and 6-foot level, car inspectors, or carmen, must often make multiple measurements to determine the height or width of a critical point on the load. The summation of these measurements can be subject to mathematical human error. In addition to the inherent limitations with regards to accuracy and efficiency, this method of measurement presents considerable safety challenges. The objective of the project was to develop a portable, cost-effective and accurate measurement system to improve the day-to-day operational process of measuring HWLs and reduce human exposure to railyard hazards. Norfolk Southern worked closely with Amberg Technologies to provide a clear overview of the current measuring methods, requirements, challenges and risks associated with HWLs. Amberg then developed a prototype system (with patent pending) and successful tests have been completed at both a point of origin for NS shipments and at a location where HWLs are received at interchange. The measuring system consists of a tripod mounted laser, a specially designed track reference target (TRT) and software designed specifically for HWL measurements. The system allows car inspectors to take measurements from a safe, strategic location away from the car. As a result, this system eliminates the need to climb on the equipment or a ladder and greatly reduces the amount of time spent on and around live tracks. In addition, initial tests indicate that this technology reduces the labor time required to measure HWLs by as much as one half while improving measurement accuracy. These tests have demonstrated that a laser-based system has the potential to greatly improve the safety, efficiency and accuracy associated with measuring HWLs.

Photogrammetric Measurement

В процессе автоматизации решения прикладных измерительных задач, в том числе на базе фотограмметрических методов, возникает проблема соответствия измерительной системы объекту и условиям измерения. Для того чтобы измерительная система позволяла заранее оценить возможность получения достоверных результатов, а также наилучшим образом подстраивалась под условия измерения, необходимо наличие специализированных алгоритмов и моделей. В общем случае такие модели ориентированы на квалифицированных технических специалистов, обладающих необходимыми знаниями в области информационных технологий. Особенностью применения фотограмметрических измерительных систем в лесной и металлургической промышленности является низкая квалификация пользователей в сфере информационных технологий, что обуславливается характером выполняемых работ и условиями привлечения. Данный фактор не позволяет решить задачу подстройки системы традиционными методами, в которых процессом настройки управляет пользователь. В этой связи в статье предлагается модель и алгоритм формирования измерительной системы по первичным входным данным, в котором процессом настройки управляет сама система. In the process of automating the solution of applied measurement tasks, including on the basis of photogrammetric methods, there is a problem of compliance of the measurement system with the object and measurement conditions. In order for the measuring system to assess in advance the possibility of obtaining reliable results, as well as to best adapt to the conditions of measurement, it is necessary to have specialized algorithms and models. In general, such models are aimed at qualified technicians with the necessary knowledge in the field of information technology. A feature of the application of photogrammetric measurement systems in the forestry and metallurgical industry is the low qualification of users in the field of information technology, which is determined by the nature of the work performed and the conditions of attraction. This factor does not solve the problem of adjusting the system by traditional methods in which the user controls the configuration process. In this regard, the article proposes a model and algorithm for forming a measuring system from primary input data, in which the system itself controls the adjustment process.
