摘　　要：针对共轭凸轮机构传动效率低和设计工作量过大的问题,对共轭凸轮机构的设计原理进行了理论推导,提出了一种基于遗传算法的共轭凸轮机构计算机辅助优化设计方法。首先,建立了共轭凸轮机构的数学模型,通过遗传算法对共轭凸轮的结构参数进行了优化求解;其次,利用MFC开发共轭凸轮机构优化设计软件,对SolidWorks进行了二次开发,自动生成了共轭凸轮三维模型;最后,将机构模型导入ADAMS进行了运动仿真,得到了从动件运动规律,并与设计要求进行了比较,验证了优化设计方法的正确性。研究结果表明:遗传算法可以使共轭凸轮机构的最大压力角接近于全局最优值,改善机构的传动效率;利用MFC进行SolidWorks二次开发求解共轭凸轮三维模型的方法,能使共轭凸轮的设计更加自动化,降低设计工作量。Aiming at the problems of low transmission efficiency and excessive design workload in conjugate cam mechanism, the design principle of the mechanism was deduced, and a computer aided optimization design method based on genetic algorithm was proposed. The mathematical model of the mechanism was established and structural parameters were optimized by genetic algorithm. The conjugate cam 3 D model was automatically generated by secondary development of SolidWorks with Microsoft Foundation Classes(MFC). The mechanism model was imported into ADAMS for motion simulation, and the motion law of the follower was obtained. The correctness of the design method was verified by comparing with the design requirements. The results indicate that genetic algorithm can make the maximum pressure angle of conjugate cam mechanism close to the global optimum and improve the transmission efficiency of the mechanism. The method of SolidWorks secondary development by MFC can make the design of conjugate cam more automatic and reduce the workload.
