摘　　要：根据振动力学以及多刚体系统动力学原理,分析了某铰接式自卸车的振动模型,同时进行合理的简化,建立了集中质量的虚拟样机模型,并在虚拟样机软件ADAMS上进行仿真。通过与试验的对比,也验证了仿真方法可行,仿真模型可靠。因此可用该模型计算随机激励下铰接式自卸车的响应,并进行整车动力学分析和悬架系统参数优化设计。This paper analyzes a kind of articulated dump truck of a vibration model with reasonable simplification according to the mechanical vibration and multi-body system dynamics theory, The centralized mass of the virtual prototype model is established and the simulation is done on the software of ADAMS. The feasibility and the reliability of simulation method and model is proved by the comparison with the test. Therefore the model can be used to compute the response of articulated dump truck, analyze vehicle dynamics characteristic and optimize the parameters of truck suspension system.
