【摘要】 本文提出了一个求解极值的方法—双向极值收敛法,它既能用于作图求解,也可以编写成计算程序作精确计算,方法新颖简单,几何概念清晰,并以此对空间RSSR机构的曲柄存在条件和运动范围进行研究。更多还原

【Abstract】 The Bidircction Extreme Convergency Method (BECM) are proposed to obtain the extreme value either by geometric method or by computer to solve out their accurate values. The method is very simple and the geometric concept is very clear.In this paper, this new method is used for the crank criterion and mobility regions for RSSR mechanism.更多还原
