摘　　要：将多体动力学理论应用于配气机构,以ADAMS/Engine为仿真平台,建立了配气机构刚柔耦合体动力学模型。通过仿真分析,得到不同转速下该配气机构系统主要运动件间的作用力,描述了配气机构的动力学性能。Flexible multi-body dynamics simulation is applied for dynamics analysis of valve train of internal combustion engine. A rigid-flexible coupled dynamics model is created based on ADAMS/Engine. Acting forces between moving parts at different engine speed are calculated by the means of simulation, thus describing the dynantics performance of a valve train.
