摘要

In order to solve the problems of heavy workload and low accuracy existing in manual measurement, a method based on laser displacement sensor (LDS) is proposed to detect wheel tread wear. First, the 2D laser displacement sensors installed on the lateral side of the track are used to collect the wheel tread data. Then, techniques including data preprocessing, coordinate transformation, data fusion, and so on are applied to process the wheel tread data combined with standard wheel tread data. Finally, the wheel tread wear can be calculated by using geometric relationship. Error analysis and field experiments show that the accuracy of the proposed method is less than 0.2 mm and has the strong anti-interference ability. The proposed method can greatly meet the actual requirements of measurement of wheel tread wear.
