反曲线铁路桥梁空间车桥耦合动力分析
Studies on Space Coupling Dynamic Responses of Vehicle and Anti-curve Bridge System
摘要
Abstract
With the help of ANSYS and UM analysis software,have built a complete three-dimensional model of bridge and vehicle,analysed the vehicle-bridge coupling vibration about three kinds of vehicles through the anti-curve bridge on lian-yan railway with different speed.According to computational analysis the displacement and acceleration of the bridge,acceleration、Spering index、derailment coefficient and reduction rate of vehicle,the results show that,when the CRH2 and Quasi-high speed train speed is less than 160 km/h,the C70 truck speed is less than 80 km/h,the anti-curve bridge has enough vertical and horizontal stiffness for the train running safety and the passenger riding comfort.关键词
