针对目前中国商用车驾驶室舒适性问题，以整车刚柔耦合多体动力学理论基础，采用ADAMS软件建立某典型商用车驾驶室及其悬置系统动力学模型，并对该模型进行了准确性验证。设计了DOE优化试验，经过仿真分析，对驾驶室悬置的刚度和阻尼进行优化，并对试验车辆按照优化参数进行改进。最后，通过道路试验表明，优化后的商用车行驶平顺性较优化前提升了9.6%，改善了驾驶室的隔振性能。
Abstract
Aiming at the comfort problem of commercial vehicle cabs, the dynamic model of cab and its mounting system of a typical commercial vehicle was established by using ADAMS software,based on the rigid-flexible coupling multi-body dynamics theory.The accuracy of the model was verified.The DOE optimization test was designed, the stiffness and damping of the cab mount are optimized by simulation analysis, and the test vehicle was improved according to the optimization parameters.Finally, the road test shows that the ride comfort of the optimized commercial vehicle is 9.6% higher than that before optimization, and the vibration isolation performance of the cab is improved.
