摘　　要：利用多体动力学软件ADAMS建立厢式运输车驾驶室悬置多刚体动力学仿真模型,以驾驶室地板处加速度均方根值为评价对象,并且利用正交设计原理与ADAMS仿真技术相结合的方法,对原车驾驶室悬置隔振系统的参数优化与匹配问题进行研究。在B级路面上分别进行了5种车速下的仿真计算,并提出对原车驾驶室悬置系统参数的优化方案,优化结果表明该方案能够明显改善整车的行驶平顺性,解决了原车隔振效果差的问题。Multi-body dynamics simulation model of van truck cab suspension was established by using multi-body dynamics software ADAMS. Appreciation of the cab floor acceleration RMS, combining the orthogonal design with ADAMS simulation, it researches on vibration isolation system parameters optimization and matching problem of the van truck cab suspension. On the B grade road, simulations at five different speeds were respectively calculated, and the optimization scheme of the original car cab suspension system parameters was put forward. The results of optimization show that the scheme can obviously improve the vehicle ride comfort and the effect of original vehicle vibration isolation.
