摘要:
［目的］作为轨道交通车辆的动力来源以及传力部件，驱动系统会在一定程度上对车辆系统的动力学特性产生影响，因此有必要对此展开研究。［方法］通过多体动力学仿真软件SIMPACK建立了国内某型采用体悬式驱动系统的高速列车单节车辆动力学模型。基于仿真分析，研究体悬式驱动系统对车辆安全性和平稳性的影响，以及对转向架构架和车体振动加速度的影响。［结果及结论］体悬式驱动系统对车辆运行安全性和平稳性都会产生不同程度的影响，除横向平稳性指标外，其余指标均随车辆运行速度的增加而增大；体悬式驱动系统增加了构架横向、构架垂向及车体垂向的振动加速度，降低了车体横向振动加速度，且该系统对于车辆构件垂向的影响较横向更加显著；体悬式牵引电机的自振频率在车体上会有所体现，需避免牵引电机和车体发生共振。
Abstracts:
［Objective］ As the power source and force transmission component of rail transit vehicles, the drive system influences the dynamic characteristics of the vehicle system to a certain extent. Therefore, it is necessary to conduct research on it. ［Method］ A dynamic model of a single vehicle section from a certain type of high-speed train that uses body-suspended drive system in China is established by the multi-body dynamics simulation software SIMPACK. Based on the simulation analysis, the influence of the body-suspended drive system on the vehicle safety and ride comfort, as well as on the vibration acceleration of the bogie frame and the vehicle body are studied. ［Result & Conclusion］ The body-suspended drive system has different degrees of influence on the operation safety and ride comfort of the vehicle. Except for the lateral stability index, all the other indexes increase with the rise of the vehicle running speed. The body-suspended drive system increases the lateral and vertical vibration acceleration of the bogie frame, and the vertical vibration acceleration of the vehicle body, meanwhile reduces the lateral vibration acceleration of the vehicle body. Moreover, the body-suspended drive system has more significant impact on the vehicle components in the vertical direction than in the lateral direction. The natural frequency of body-suspended traction motor may be reflected on the vehicle body, so the resonance between the motor and the vehicle body needs to be avoided.
