曲线间中心线的自动创建方法

Automatic Creation Method of Center Line between Curves

介绍一种自动创建曲线间中心线的方法,基于等距原则和有限元法,使用二分法调整中点在直线上的比例参数,得到曲线间的中心线,并以两条曲率非线性变化的自由曲线和某复合材料导弹弹翼为例,验证该方法的可行性和有效性。

A method of automatic creating center line between curves is introduced.Based on equal distance principle and finite element method,and by binary division algorithm,the ratio parameters with its midpoint along the straight line are adjusted to abtain the center line between curves.The effectiveness and efficiency of the proposed method are verified with the two free curves with non-linear curvature and a composite missile wing as examples.
