Interferometric Measurement

Interferometric measurement of length by fringe-counting, using a laser source, is a precision technique suitable for both engineering and laboratory applications. The limitations of such systems, in respect of speed and straightness of movement, are considered. Equations are given to assist the specification of the optical requirements and mechanical tolerances.

The article describes the results of research and development undertaken to develop a compact, optical measurement system for measuring the elements of track infrastructure. The article describes the main features of the optical measurement systems and the results of the research project. The author presents two examples of the implementation of this technology in the portable diagnostic devices: electronic trolley and in the toll for the creation of 3D models of turnout crossings.

Since the 1956 Edition of the ASME Boiler and Pressure Vessel Code Section VIII (ASME B&PV Code) [1], the Out-of-Roundness of circular sections of pressure vessels subject to external pressure have been inspected using a segmental template per paragraph UG-80(b)(2). Newly approved ASME Code Case 2789 “Laser Measurement for Out-of-Roundness Section VIII, Division 1” to the ASME B&PV Code expands the out of roundness checking to allow the use of laser measurement systems. Today with large vessels approaching 60 feet (18.2 m) in diameter, laser measuring systems allow an expeditious and cost effective method of inspection for out-of-roundness. The Code Case allows the fabricator to use measurements obtained from laser measuring to either verify the vessel in the arc segments or the entire vessel circumference is held to a circularity tolerance. The second option is similar to the requirements of European Standard EN 13445 (EN 13445) [2] which uses circularity. This paper will explore the origin and objective of the template and presents how laser measuring systems make use of the latest technology available to check for out-of-roundness. The paper will address laser measuring systems, procedures for taking measurements, and processing of the data into a format that can be verified by Authorized Inspectors.

We propose a new calibration method for 3D laser measurement systems used for inspecting the insides of industrial parts such as vessels and pipes. We developed the proposed calibration system using a cylindrical artifact such that the calibration is simple and easy to perform. We simulated and analyzed the proposed cylindrical artifact calibration method and the results demonstrate its adequacy.

Working Processes

The central question when creating measurement systems is the development of measuring converters. For fuel injection process control fuel pressure check converters are used. Existing systems use autonomous sensors of various types that require additional structural elements that influence the process of fuel injection in the system of fuel supply inclusion. Promising is the creation of systems with combined converters, based on the basic constructive elements. Creating this kind of measurement systems is the subject of development and research, the results of which are presented in this report. One of the promising directions of development of systems of control of working processes of diesel engines is the use of combined transducers on the basis of the structural elements of the engine. This solution does not require the use of separate sensors and provides continuous monitoring of the considered parameters.
