摘要
本文首次应用连续法研究了空间ＲＳＳＲ－ＳＣ机构实现四个精确位置的刚体导引综合。首先将ＲＳＳＲ－ＳＣ机构分解成两个ＲＳ二副杆和一个ＳＣ二副杆，然后分别导出两类二副杆多项式形式的综合方程组，最后应用连续法直接求出综合方程组的全部解。本文的综合方法，既不需构造初始机构，又可求得多组机构方案，对其它空间机构的运动综合也具有参考价值。
In this paper,synthesis of a RSSR-SC mechanism for rigid-body guidance with four precision points is presented origi-nally The mechanism is broken up into two RS dyads and one SC dyad so that they can be synthesized respectivelyi,Polyno-mial equations are formulated for each dyad and continuation method is introduced to fond their solutions.The procedure pro-posed in this paper can be used for synthesizing other kinds of spatial mechanisms.
