| 摘 要： | 对于平面凸轮机构的运动分析可以用高副低代的方法将其转化成平面连杆机构来进行,而高副低代后关键的问题是如何在书籍平面凸轮廓线的基础上求解凸轮的曲率半径.另外,在平面凸轮机构的综合中,一般也要验算凸轮轮廓曲线的曲率半径.本文详细介绍了如何用斯梯林插值公式求解凸轮廓线为等间隔离散点的平面凸轮曲率半径方法,并给出了一个例子加以验证.

| Abstract: | The kinematic analysis of a planar cam mechanism can be realiaed by the method that the higher pair is substitute for lower pair, and then it is equivalent to a planar linkage. The main point by the way is how to calculate the radius of curvative of planar cam profile. In the meantime the radius of curvative of the planar cam profile should be al- so tested in the synthesis of the planar cam mechanism. A method of determining the radius of curvative of a planar cam profile by Sterling Differentiation is proposed, and then an example is given to demonstrate it. |
