按升程效率最佳优化设计直动从动件凸轮机构

Optimum Design of Disk Cam Mechanisms with Rectiliner Translation Roller Follower for Maximum Efficiency of Lift Travel

本文提出了以升程效率最佳为目标函数,对凸轮机构进行优化设计的新方案.该设计方案既能避免机构自锁,又提高了效率,减小了机构尺寸.文中给出的实际算例表明,利用该方案,可以得到令人满意的凸轮机构.

A new method of optimum design of cam mechanisms is presented in this paper, Its objective function is maximum efficiency of lift travel. The design method can not only avoid self-locking of the mechanism, but increase the efficiency and decrease the size. The practical calculation example given in this paper shows that using the method a satisfactory cam mechanism can be obtained.
