在建立五转向架城轨磁浮车辆动力学模型的基础上,首先进行考虑侧风和行驶风阻的车辆直线加速工况仿真,给出重要构件的受力和变形特征;然后开展5种不同侧风时车辆加速过程的仿真分析,比较不同风速时,牵引拉杆和抗侧滚梁吊杆等构件的受力规律。在仿真结果分析的基础上,指出了五转向架城轨磁浮车辆设计时应注意的一些问题。
Based on the establishment of the dynamic model of the five-bogie MCLM, the simulation of the straight-line acceleration of the vehicle considering the crosswind and windage resistance is carried out first, and the stress and deformation characteristics of the important components are given. Then five different crosswind The simulation analysis of vehicle acceleration process is carried out to compare the force of traction rod and anti-roll bar boom when comparing different wind speed. On the basis of the simulation results, some problems that should be paid attention to in the design of the five bogies TRC are pointed out.
