Derailment Analysis of Tilting Railway Vehicles with Wind Loads

Abstract:

In this article, equations of motion of tilting vehicle system, considering the lateral displacement, roll angle and yaw angle of each wheelset, the lateral displacement, vertical displacement, roll angle and yaw angle of the truck frame and the car body, are derived. The tilting vehicle system is modeled by a tilting train system with 24 degree-of-freedom (24-DOF) system traveling on curved tracks. Considering the cross-wind forces acting on the car body in the lateral, vertical and roll directions, the influences of the vehicle speeds on derailment quotients are investigated. Additionally, the effects of the vehicle speeds on the derailment quotients are presented and compared with wind loads and the various tilting angles.
