矫直零件中心线方程的分析

Centerline equation of straightening parts

以条材类零件受到集中力作用产生的弯曲中心线为研究对象,通过拟合、插值等方法,分析得出一种方便、快捷描述弯曲中心线的曲线方程。可方便、快速获得校直曲率与曲率变化梯度参量。

Curvature and curvature changing rate are important parameters in straightening, and can be obtained rapidly when there is a convenient curve equation. In this paper, the bending centerlines caused by the imposed concentration force on the rods are taken as the research objects. With the methods of fitting, interpolation, etc, a eurvilinear equation which can conveniently and quickly describes the bending eenterline has been obtained. In application, it can conveniently and quickly get such parameters as straightening curvature and curvature changing rate.
