Service Performance and Tracking Test for High-Speed Train

In recent years, rail transit developed rapidly, as the main transport. High-speed train is a wide concern. In actual operation, with the train's service time increasing, dynamic performance of key components in train has also changed and some deterioration of dynamic performance threatens the security operation of high-speed train. Tracking test is monitoring test which aims at performance, reliability, and security when the train is in service. Through the tracking test, we can get the variation tendency of relational parameter, to avoid accidents. This paper expatiate the necessity, test contents and commands for design tracking test system. Paper concretely introduces the situation of tracking test for high-speed trains, using data of tracking test to analyze the influence to dynamic performance from tread wear. By tracking test will be enhanced the safety of train operation.
