摘　　要：利用SolidWorks软件建立了对数螺旋线型凸轮机构和普通凸轮机构的实体模型,并进行了运动学仿真,然后利用ANSYS/LS-DYNA软件对两种凸轮机构进行了动力学分析,得到了凸轮机构主、从动件最大应力随时间的变化情况。对对数螺旋线型凸轮机构与普通凸轮机构的运动学、动力学仿真结果进行了对比分析,发现对数螺旋线型凸轮在工作过程中传动更加平稳,主、从动件的受力变化范围小,且应力平均值小,表明对数螺旋线型凸轮机构要优于普通凸轮机构,具有推广应用价值。The solid models of the logarithmic spiral cam mechanism and common cam mechanism are es- tablished by using SolidWorks, and the kinematics simulation is carried out. Then, by using the software of ANSYS / LS - DYNA, the dynamics analysis of the two kinds of cam mechanism is carried out, and the varia- tion situation of the maximum stress of cain mechanism and the follower changing with time is obtained. By con- trast analysis between the dynamics simulation and the kinematical simulation of logarithmic spiral cam mecha- nism and common cam mechanism, find that the logarithmic spiral cam mechanism drive is more steady during the operation, and the force variation and the average stress of cam and follower are lower, which indicates that the logarithmic spiral cam mechanism is superior to common cam mechanism, and possessed of popularization and application value.
