摘　　要：文中以商用车驾驶室悬置系统为研究对象,构建驾驶室悬置系统多体刚柔耦合动力学模型,探讨了模态分析并进行了理论验证,通过整车道路采样测试技术和虚拟迭代技术获取了一般公路路况下的驱动信号。研究了一般公路随机激励下的平顺性仿真,并借助国标规范进行了振动舒适性评价,仿真结果表明:悬置系统性能不符合设计要求,在此基础上,采用正交设计对悬置系统参数进行优化匹配设计,得到了悬置系统性能参数的最优解,新的悬置系统满足了设计要求,提升了振动舒适性。In this article,with the focus on the commercial vehicle's cab suspension system,the multi-body rigid-flexible coupling dynamic model is set up on the cab suspension system,and efforts are made to conduct the modal analysis and the theoretical verification;the driving signals under general highway conditions are obtained with the help of the vehicle road sampling test technology and the virtual-iteration technology.Then,smoothness performance of general highways is simulated with random excitation,and vibration comfort is evaluated by means of the international standards.The simulation results show that performance of the suspension system does not meets the design requirements.On this basis,the orthogonal design is used to the suspension system's performance parameters are matched in an optimized manner,and the optimal solution of the performance parameters is worked out.The new cab suspension system meets the design requirements and enjoys a higher standard of vibration comfort.
