Vibration and stability analysis of CRH3C high-speed train

基于ADAMS仿真软件,以CRH3C型高速动车车辆参数为原型,搭建整体为14个自由度的有限元模型。建立了理论力学模型,利用MATLAB软件建立微分方程并求解,运用数学方法研究车辆系统的运行平稳性。采用Sperling及车体横向垂向加速度等指标,结合动力学仿真数据对列车运行的平稳性进行了综合分析与对照验证,为今后展开该方面的研究提供数据参考。

Based on ADAMS simulation software and CRH3C high-speed train vehicle parameters as the prototype,a 14-degree-offreedom finite element model was built;The theoretical mechanical model was established,the differential equations were established and solved by MATLAB software,and the vibration characteristics of the vehicle system were theoretically studied by mathematical methods;Using Sperling and lateral and vertical acceleration values of the vehicle body,combined with dynamic simulation data,the comprehensive analysis and comparison verification of the train running stability were carried out,which provided data theoretical support for future research in this area.
