Paper Abstract

The defects of wheel sets seriously affect the train operation safety which of problem to be solved. A method of detecting the wheel sets defect is investigated through the three-dimension profile. The three-dimension profile reconstruction of wheel sets is realized by combining two-dimension CCD imaging with line laser and encoder. The theoretical derivation of detecting principle is established, and the factors of influencing the measurement accuracy are analyzed. An algorithm is set to processing measurement data, the main parameters of wheel set are obtained, including flange thickness, flange height, vertical wear (QR) and tread wear. The results of simulations and field experiments show that the proposed method can detect the faults on the wheel correctly, and satisfy the requirements of high efficient and accurate.
