本文主要解决旋转面天线反射面筋条曲线的计算问题。筋条曲线实质上就是旋转曲面与某一平面相交的曲线。这里主要采用曲线样条插值方法来定义主曲线,用迭代方法来求解筋条曲线。其主要步骤是:首先,用曲线样条方法来定义旋转曲面的主曲线,本方法能精确地表达主曲线,其RMS误差能达10~(-5)量级;其次,用迭代法求解筋条曲线上的51个点,为了加速收敛速度,采用弦切法近似求解,而且这51点的分布是两端密、中间稀,这样能在保证精度前提下减少计算机计算时间;最后,以这51点为基点再次采
This article mainly solves the calculation problem of the curve of the gluten curve of the rotating plane antenna. The rib curve is essentially the curve that the surface of revolution intersects with a certain plane. Mainly using curve spline interpolation method to define the main curve, iterative method to solve the tendon curve. The main steps are as follows: Firstly, the main curve of the rotating surface is defined by the curve spline method. The main curve can be accurately expressed by this method, and its RMS error can reach 10 ~ (-5). Secondly, In order to speed up the convergence rate, the chord-cut method is used to approximate the solution. The distribution of the 51 points is dense at both ends and thin in the middle, which can reduce computer calculation time under the premise of ensuring the accuracy. Finally, 51 points as the base again mining
