摘　　要：基于多体动力学理论,建立了柴油机整机的刚柔多体动力学模型和单独配气机构刚柔耦合多体动力学模型,对柴油机配气机构进行动态性能研究,获得了柴油机配气机构的运动学、动力学参数。对比上述两种模型的计算结果发现:利用柴油机整机刚柔耦合多体动力学模型,不仅能够获得配气机构的运动学、动力学参数,还能获得许多柴油机工作过程中的性能参数,能够较全面地评价配气机构的性能。因此,柴油机整机刚柔多体动力学模型对分析柴油机配气机构的动力学性能具有实际意义。On the basis of multi-bodied systematic dynamics theory,the rigid-flexible coupled dynamics model of the whole diesel engine and separate model of valve trains were built.Based on the model,dynamics simulation study was conducted on the valve trains,then the kinematics and dynamics parameters of the valve trains were obtained.Comparison between the two models show that the whole diesel engine model can not only obtain the more reliable kinematics and dynamics simulation results,but also get the performance parameters of diesel engine＇s working process,so it can evaluate the performance of valve trains more completely and is more valuable in the study of valve trains＇ dynamics performance.
