Analysis of Curve Negotiation of High-Speed Vehicle Influenced by Line Parameters

In this paper, aimed at the problem of curve negotiation in railway, high-speed vehicle-track dynamical model is built. Secondary development is done on the basis of 60kg/m rail section and LM wheel tread used in China. Based on high-speed railway and passenger dedicated line, discussion is done on influence of safety and comfort of vehicle caused by the line parameters such as curve radius, cant, length of transition curve and rail cant, when the train negotiate railway curve at the speed of 200km/h. The research will be of significance for the construction of high-speed railway and passenger dedicated line in the future.
