high-order grating

This paper present a new method to interpolate high order curve which is used in CNC system,at the time use this method is samed to interpolate a three order curve,the result prove that this method is high efficient and precise.

提出了一种在数控加工中对高次曲线方程进行插补的计算方法,同时利用此方法对实际曲线进行了插补计算结果,证明此方法为一高效精确的插补方法。

The parabola of higher order is taken as the axial curve of three-hinged arch subjected to the action of concentrated forces,uniform distributed force and stuffing load.

针对集中载荷、均布载荷以及填料重量载荷同时作用下的三铰拱结构,以高次抛物线为拱轴线方程,提出了优化拱轴线的方法,建立了以各控制截面弯矩平方和为最小的优化目标函数和约束方程。
