摘要
以车辆—轨道耦合动力学为理论基础,通过有限元软件ABAQUS和多体动力学软件SIMPACK联合仿真,并与在实际轨道交通试验线上进行的车辆轨道动力学性能实验进行对比分析,旨在研究车辆及轨道的各项动力学性能指标随扣件刚度变化的规律,以期从车轨系统减振的角度出发,为扣件设计时刚度的选择提供更加合理的依据。
Based on vehicle-track coupling dynamics,is aiming at the research into the principle of how the various dynamics performance indexes of vehicles and tracks change as the fastener stiffness changes. This paper utilizes the combined simulation of both the finite element analysis software ABAQUS and the multi-body system dynamics software SIMPACK,and makes an experiment into the vehicle-track coupling dynamics performance in the practical rail transit lab. From the perspective of the shock absorption of the vehicle-track system,the principle concluded in a comparison between the results of the simulation and the experiment can provide a much more reasonable evidence for designing a fastener.
