Study on the Safety of High-Speed Trains under Crosswind

Abstract

Aiming at high-speed passenger train of CRH2,the dynamic characteristic of high-speed passenger train under the influence of crosswind were researched with dynamic model built three vehicles which contains the head vehicle, the trailer and the tail vehicle by the CAE software SIMPACK in this dissertation. Basing the wind impact the dynamic performance of an operating passenger train in difference operating trains cross conditions on ground of the result of simulating computation on the Aero dynamic loads of cross affect on the train on the same operating conditions. We calculation and analysis on dynamic model and figure out the dynamic parameter and safety operating criterion including lateral force, derailment coefficient, wheel unloading rate, thereby discuss the safety issue of train under the two trains cross, then forecast the high-speed passenger train’s safety operation.
