Prospects for the further development of the oil and gas industry are mainly associated with the development and commissioning of high-rate fields. In this regard, the production of more economical and durable equipment by machine-building enterprises, an increase in the level of its reliability and competitiveness, as well as further improvement of technological production processes, is of paramount importance. The evolution of technology in a broad sense is a representation of changes in designs, manufacturing technology, their direction and patterns. In this case, a certain state of any class of TC is considered as a result of long-term changes in its previous state; transition from existing and applied in practice vehicles to new models that differ from previous designs. These transitions, as a rule, are associated with the improvement of any performance criteria or quality indicators of the vehicle and are progressive in nature. The work is devoted to the study of the evolution of the quality of high-pressure valves during the period of their intensive development. Keywords: technical system, evolution of technology, high-pressure valves, shut-off devices, gate.

It is an important factor that tool size affects the quality and efficiency of complex curved surface of CNC machining. This paper starts with analyzing the functional relationship between the tool size and the quality and efficiency of complex curved surface, gives the selection method of optimal minimum tool which can ensure the precision of machining curved surface, establishes optimal selecting algorithm of reasonable large size tool with the most high efficiency as the objective, and for the curved surface of complex geometric features, puts forward tool combination selection method with effective area ratio of tool machining as a reference. Application examples show: the optimal selecting strategy of tool size in this paper, under the premise of adequately ensuring the machining quality of complex curved surface, can effectively improve the whole machining efficiency.

One of the urgent problems of modern industrial enterprises is the problem of their technical development. The most common direction of technical development is the technical re-equipment of industrial enterprises. This is a very long and costly process, requiring both from the management of the enterprise and from its employees of high qualification, the ability, and skills to make quick decisions and predict the outcomes of these decisions. Currently, the market for technical and technological equipment is represented by many kinds of different industrial machines, aggregates, mechanisms of different manufacturing firms, different levels of complexity, productivity, energy intensity, and, of course, different costs. The analysis of the market, the choice of suppliers of production equipment, the formulation of terms of delivery and payment, installation, assembly, and installation of equipment at the enterprise, commissioning and subsequent technical support are all elements of the process of renewal of fixed assets called technical re-equipment.Technical re-equipment includes raising the technological level of production, which includes the use of additional new equipment (both in the case of physical and moral obsolescence).During this event, either modified tools will be used in the production of old products, or the quality of the products will change, or a completely new product will be produced, or all taken together. In addition, the concept of technical re-equipment can include the re-qualification of personnel during the re-equipment process and bringing technologies in line with environmental norms and standards.

Printing Techniques

The construction industry has embraced digitisation and industrialisation in response to the need to increase its productivity, optimise material consumption and improve workmanship. Additive manufacturing (AM), more widely known as 3D printing, has driven substantial progress in these respects in other industries, and a number of national and international projects have helped to introduce the technique to the construction industry. As with other innovative processes not covered by uniform standards, appropriate assessments and testing methodologies to control the quality of the 3D-printed end products, while not obligatory, are advisable. This article shows that regulation is not an obstacle to the use of an innovative product, such as 3D printing, by proposing quality-control tests and an assessment methodology, in the understanding that standardisation ensures the viability of a technology. The information, including the methods and results, is based on the authors’ experiences in the development of three research projects pertaining to 3D printing. This paper also discusses whether the performance of the materials used in 3D printing could be superior to traditional ones.

The theory, the algorithms and program package BLADIS (BLAded DIsk Simulation) for strength calculations of rotating flexible blade-disk-shaft assemblies have been worked out. The formulation is based on a finite element analysis of the rotating cyclic structures and modal reduction. The stresses in different zones of the structural components due to influence of centrifugal and temperature forces using static analysis and vibration are calculated. The results obtained show, how shaft flexibility influence on stresses and frequencies. Analysis of influence of blade geometric parameters on disk-shaft stresses is presented. The results obtained by dynamic analysis show that the chosen reduction does not reduce the quality of the model and illustrate its capability to deal with rotating shafts usually calculated using the rotordynamic approach. Finally, the possible dynamic interactions between shaft and disk components are described. This information is used for bladed disks and rotors optimization leading to a reduction of resonance displacements, stress levels and shifts of natural frequencies of rotating flexible blade-disk-shaft assemblies from dangerous resonances. The numerical results are carried in leading machine building companies in Russia.

Aided Design

The actual task in the field of computer-aided design of machine-building objects is to increase the level of automation of structural-parametric analysis of design solutions due to the repetition of their use, reducing the number of design operations and ensuring the corresponding competencies of designers. Developed methods and algorithms should ensure the acquisition of the necessary competencies for the designer for successful project activities in the field of computer-aided design, increasing the effectiveness of training. The system of analysis of design solutions should improve the quality of design solutions implemented in CAD KOMPAS-3D. In this paper, an overview of methods, systems and tools for analyzing design solutions implemented in the CAD-3D environment. The main features of such systems are described, their main disadvantages are identified: the lack of functions for determining non-optimal sequences of design operations, the inability to automatically rebuild a three-dimensional model of a machine-building product on the basis of analysis of the design model tree. A complex system for the analysis of project solutions and the training of a designer was developed and implemented, based on methods, models and algorithms for analysis and adaptive learning. The results of a computational experiment are presented, on the basis of which it can be concluded that the use of developed software enhances the efficiency and quality of the designer's training in the processes of constructing three-dimensional solid-state machine-building products in CAD KOMPAS-3D.
