摘要

A new wheel size online detection system for subway vehicle based on laser displacement method is introduced to solve problems such as large workload and low accuracy of manual measurement for metro wheelset. This paper describes the system structure, proposes the design of hardware and software, and expounds the principle of using laser displacement sensor to realize the measurement of the thickness of wheel flange, height of wheel flange, and wheel diameter parameters. In order to verify the usability of the system, the field round test and the vehicle test are carried out, and the measurement results between the online system and workman are compared. The results show that the detection system has the advantages of accurate measurement and good consistency, and can replace the existing manual measurement to meet the requirements of wheel size measurement.
