| 摘 要： | 以城市客车为平台，分析其车辆动力学各子系统的型式和参数，根据现有积累的试验测试数据，采用Trucksim软件建立整车多体动力学模型。在此基础上，对城市客车制动、转弯、冲击及扭曲等典型运行工况进行动态模拟，提取出悬架系统各部件的受力情况，包括弹簧、减震器等。结果表明，城市客车在冲击工况下悬架整体受载最大。该仿真结果能够为城市客车有限元模型各典型工况下的载荷施加提供精确的输入，有利于提高受力分析的准确度。

| Abstract: | With the city bus as a platform, the types and parameters of each subsystem of vehicle dynamics were analyzed, and the multi-body dynamics model of the vehicle was established by Trucksim software according to the existing accumulated test data. On this basis, the dynamic simulation of the typical working conditions such as braking, turning, impact and torsion of the city bus was carried out, and the force of each component of the suspension system, including spring and shock absorber, was extracted. Results show that the overall load of the suspension of the city bus is the largest under the impact condition. The simulation results can provide accurate input for the load application of the finite element model of the city bus under various typical working conditions, which is beneficial to improve the accuracy of the force analysis. |
