Abstract:
Purpose. Improvement of methods and tools for experimental evaluation of the quality and safety indicators of freight wagons by enhancing the theoretical foundations, methodological approach, and instrumental support for testing. It is proposed to implement software and hardware systems instead of laboratory wagons to determine the quality indicators of wagon movement, as well as to provide recommendations for assessing the dynamic performance of rolling stock.
Methodology. The paper examines the features of monitoring the strength and dynamic characteristics of freight wagons using modern measurement systems under operating conditions. It describes a method for measuring wheel-rail interaction forces by determining deformations at control points and highlights the general requirements for force measurement systems to ensure traffic safety. The study provides recommendations for direct measurements to assess the stability margin of wheelsets (quality indicators of movement), which will help prevent transport incidents. Additionally, emphasis is placed on the need to improve methodological and software support for evaluating movement quality indicators.
Findings. A transition from laboratory wagons to mobile software and hardware systems for rolling stock testing has been proposed, which will enhance the efficiency and accuracy of movement quality evaluation. The dependency areas of stress formation in the disk of a standard freight wagon wheel under vertical and horizontal force loads have been identified. An improved strain gauge scheme for measuring wheel-rail interaction forces has been proposed.
Originality. General requirements for a mobile software and hardware system for measuring and evaluating the quality indicators of freight wagon movement under operating conditions have been developed, and field tests using this system have been conducted.
Practical value. The obtained research results make it possible to formulate general requirements for a mobile software and hardware system for measuring and evaluating the quality indicators of freight wagon movement under operating conditions. These results should be used in the development and design of systems for railway rolling stock aimed at monitoring traffic safety by measuring strength and dynamic parameters. This, in turn, will enhance the safety of railway transportation.
