摘要
在给定直线上一点和直线方向以及两个机架点的情况下 ,得到可以综合出具有鲍尔点的“梯形”四杆直线机构的方法。分析了曲率驻点曲线蜕化的原因和结果 ,利用蜕化了的曲率驻点曲线和欧拉 -萨法利方程得到了综合四杆直线机构的公式。机构经过给定点时连杆平行于机架。
We present a method for synthesizing “trapezoid”four bar straight line linkage when two fixated points and a straight line are given. The cause and result of circle point curve degeneration were discussed. With the help of degenerated circle point curve and Euler Savary equation, a method to synthesize four bar linkage, whose coupler curve has four infinite points contact with its tangent, was presented. When the four bar linkage passed the given points the component(AB)is parallel to frame(A 0B 0).
