摘　　要：引起内燃机振动的一个重要因素是其曲柄连杆机构往复运动产生的惯性力和惯性力矩。应用多体动力学相关理论,基于动力学仿真软件ADAMS和Pro/E,建立了多缸内燃机的虚拟样机参数化实体模型,通过MECHANANISM/Pro接口模块将所建模型导入ADAMS中进行仿真分析,得到了活塞、曲轴、连杆等主要运动部件的运动规律和受力情况,仿真结果与内燃机实际工作情况基本一致,为内燃机曲轴连杆机构的进一步优化设计提供了依据。The inertial force and moment produced by the crank - rod mechanism is an important factor of the vi- bration of multi - cylinder internal combustion engine. Based on the dynamics simulation software ADAMS and Pro/E, the virtual prototype model of crank connecting rod of multi - cylinder internal combustion engine is established. The virtual prototyping parametric model is imported into ADAMS software by MECHANANISM/Pro module interface, and the characteristic of movements and force of the main parts such as piston, crank, connecting rod are obtained. The re- sults show that the simulation results are accordant with the true working state of internal combustion engine, the refer- ences for the further design of internal combustion engine is offered.
