【摘要】 基于“伪刚体模型法” ,分析研究了当给定从动件的变形或给定其运动规律时大变形柔顺机构原动件的驱动问题。首先对柔顺机构中不同柔性元件的运动轨迹进行了分析 ,给出了其“伪刚体模型”中主要结构参数的确定方法。在此基础上 ,研究了当从动件产生预期的变形或满足给定的运动规律时 ,求解原动件驱动力矩的一般方法。最后通过算例说明了方法的有效性。更多还原

【Abstract】 Based on the pseudo-rigid-body model method,the a ctuation characteristics of a large-deflection compliant mechanism system is st udied when the deflection or motion path of the follower member is given. Firstl y,the configurations of different flexible members in the compliant mechanisms are analyzed. Secondly,the main structural parameters of the pseudo-rigid-bod y model are determined. Thirdly,on the basis of the first two steps′ results, a method of solving the driving moment is presented when the motion or deflectio n of the follower is known. An example shows that this method is valid.更多还原
