摘要： 本文将最优控制理论用于高速凸轮-从动杆系统的设计，对凸轮-从动杆系统存在着众多而又相互矛盾的设计要求，本文提出的性能指标泛函对众多的设计要求都有显著效果，该优化设计法与传统的多项式设计方法相比较，使最大接触力、接触应力以及能量损失分别减小了19%、10%及17%，同时使凸轮-从动杆分离的凸轮工作转速提高6%。在减小压力角、凸轮曲率以及从动杆力等重要性能方面也有显著改善。

Abstract: Optimal Control Theory is applied to high-speed cam-follower systems design in this paper. There are a number of important competing characteristics that a good cam design must satisfy. A performance index functional proposed in this paper is very effective to improve the competing characteristics. The optimization design approach developed, compared to current polydyne cam design, decreases the maximum contact force, contact stress, and energy loss 19%, 10% and 17% of the polydyne cam values, while increasing the can speed for cam-follower separation by 6%. Significant improvements are also made in the pressure angle, cam curvature, and the follower force.

Key words: 凸轮, 优化设计, 最优控制
