摘要
研究了高速列车弹性车体对整车动力学性能的影响。为分析弹性车体对列车运行的影响,首先建立了车体有限元模型,计算了车体的模态,并生成模态中性文件将其导入VI-Rail软件,然后将柔性车体和前、后转向架子系统组装成刚柔耦合整车模型,分析了其对运动稳定性、运行平稳性、运行安全性的影响。通过与刚性车体动力学模型仿真结果的对比表明:弹性车体模型会使整车各项动力学性能指标略大于刚性车体模型。
The effect of the high speed train elastic body on the dynamic performance of the vehicle is studied.To analyze the influence of elastic body,first of all,the FEM model of the body is established,the modal of the body is calculated,then the modal neutral file generated by ANSYS is imported into the VI-Rail software.The flexible body,the front and rear bogie frame subsystems are assembled and rigid flexible coupling vehicle model is built,and its influence is analyzed on motion stability,stable operation and operation safety.By comparing with the rigid multi-body dynamics model,the simulation results show that vehicle with flexible body has better dynamic performances than with rigid body.
