| 摘 要： | 为了研究弹性构架对车辆系统振动响应的影响,结合FE软件ANSYS和MBS软件SIMPACK,通过在SIMPACK前处理程序FEMBS中生成弹性构架的标准输入文件,在SIMPACK中建立刚柔耦合的车辆系统动力学模型,并把转向架构架考虑为弹性体.通过仿真计算,获得了车辆系统的位移、加速度、振动频率等振动响应特性.对比分析结果表明,弹性构架对系统的振动响应强于刚性构架,且加宽了系统的振动频率范围.

| Abstract: | In order to research the effect of the elastic frame on the vibration response of the vehicle system,with the combination of the FE software ANSYS and MBS software SIMPACK,through generation of the standard input document of the eleastic frame in the SIMPACK pre-processing program FEMBS,the dynamics model of rigid-flexible coupling vehicle system is set up in SIMPACK,and the bogie frame is considered as an elastic body.Via simulation calculation,such vibration response features as displacement,acceleration,... |
