摘要
基于五杆机构的基本理论和三角形稳定性原理,提出能够精确实现“任意给定轨迹”的RPRPR五杆机构;针对该机构特点,提出“轨迹外接圆”、“运动时间特性”等概念;在此基础上,建立精确实现“任意给定轨迹”五杆机构的优化模型;基于W indows条件下,实现了可视化程序;实例表明机构、概念和方法的正确性。
On the basis of the basic theory of five-bar mechanism and the theory of triangle stability, the RPRPR five-bar mechanism realizing accurately ＂the given tracks at random＂ is put forward in this paper. The concepts of＂ tracks＇ circumcircle＂ and＂ movement time characteristics＂ are brought forward according to the mechanism＇ characteristics. The optimization model of five-bar mechanism realizing accurately ＂the given tracks at random＂is built and visualizing program can be realized in windows. At last the instance indicates that the mechanism and the computing methods are correct.
