基于虚拟技术的空气悬架客车平顺性仿真分析

摘要

以国内某空气悬架客车为研究对象，利用多体动力学软件建立其整车多体动力学仿真模型并进行平顺性仿真分析，所得仿真结果与实车道路试验结果基本吻合，证明仿真模型是可靠的。仿真结果对空气悬架客车的开发与改进具有一定的指导意义。%A domestic air-suspension bus for the study ,use multi-body dynamics simulation software build a mechanical simula-tion model and carry the simulation of comfortable capability .Simulation results and the results of real road test are basically con-sistent.The simulation model is reliable .Simulation results are valuable to the development and improvement of air-suspension bus .
