等误差及等步长直线逼近渐开线节点的改进算法

Improving Calculating Method of Nodes Based on Straight Line Approaching Involutes with Equal Errors and Equal Step Length

文章提出了一个直线逼近渐开线时节点坐标的改进算法。其关键点是导出了求估算步长的一个简单公式,从而很容易的由已知节点坐标求出到下一节点的坐标增量。计算结果表明,节点坐标都落在理论曲线上,而且实际步长与估计步长相差极小。

This paper presents a improving method of approaching involute with straight line. The key point of this method is that a simple formula has been derived for estimating step length .Therefore it is easy to find the unknown node coordinate from known one. The calculating result shows that all node coordinates lay on theoretical curve and the difference between practical and estimating step length is very small.
