对内燃机曲柄连杆机构的工作性能进行仿真分析是该产品设计过程中的重要组成部分。运用机械系统仿真软件ADAMS,建立了曲轴、飞轮、连杆、活塞在内的虚拟样机模型,之后将曲轴视为柔性体,利用PRO/E建立曲轴的三维实体模型,导入ANSYS进行模态分析,生成中性文件,再导入ADAMS中生成曲轴的柔性体模型来替换刚体模型,构造刚柔混合体模型,通过对模型的多体动力学仿真,得到曲轴连杆和活塞的运动特性曲线,为以后内燃机的优化设计及疲劳分析提供参考。 |

Its crucial to have a simulation study on the working characteristic of crank connecting rod mechanism in the design of internal combustion engine. In this paper, an engine model including crankshaft, flywheel, connecting rod and piston is built by using the mechanical system simulation software ADAMS. Then, the crankshaft is regarded as flexible body. By using PRO/E software, three dimensional solid model of the crankshaft is established and the neutral document is obtained by importing it into ANSYS for modal analysis. At last, the above mentioned neutral document is ducted into ADAMS software and the system of rigid flexible mixed dynamics model is constituted. By multi body dynamics simulation, this paper obtains dynamic characteristic curve and parameters of engine crankshaft and connecting rod and piston, providing a reference for the optimization of the design of an internal combustion engine and fatigue analysis. |
