摘　　要：应用双向极值收敛法，研究在空间任意交角情况下，ＲＳＳＲ机构的曲柄存在条件和运动范围，并以几何方法求解双向极值，也可以编成程序作精确计算．The Bidirection Extreme Convergency Method(BECM)is proposed to obtain the ex-treme value either by geometric method or by computer to solve their accurate values. Themethod is very simple and the geometric concept is very clear. In this paper,this new methodis used for the crank criterion and mobility regions for RSSR mechanism with arbitrary shaftangle.
