摘　　要：以L-10/7型空压机曲柄连杆机构作为研究对象,通过SolidWorks软件建立曲柄连杆机构的三维模型并进行虚拟装配,用其motion模块对曲轴的进行动力学仿真,得到曲轴载荷的变化规律。利用ANSYS Workbench和Solid W orks之间的无缝连接,将曲轴模型导入到ANSYS W orkbench中,对曲轴进行强度分析,得到曲轴的应力和应变的分布情况,分析表明曲轴强度和刚度均达到要求。同时对曲轴进行了预载荷模态分析,分析表明曲轴具有良好的动态特性。分析结果为空压机的曲轴结构改进和优化设计提供参考。The model of L- 10/7 type air compressor mechanism is established using SolidWorks to realize virtual assembly.Dynamics simulation of crankshaft is carried out using the motion module to obtain the load variation law of the crankshaft. By using the connection between ANSYS workbench and SolidWorks, the crankshaft is imported into ANSYS Workbench. The distribution of stress and strain of the crankshaft is obtained using strength analysis, which shows that the crankshaft strength and stiffness can meet the design requirement. The modal analysis of the crankshaft is also carried out, the dynamic characteristic of the crankshaft is verified.The analysis results provide reference for optimization design of the air compressor crankshaft.
