无模旋压成型抛物面天线反射面是一个复杂的力学过程。由仿形数控装置控制成型轮沿着给定的平面曲线进给,成型轮在毛胚表面上压延,决定了反射面的最后形状。如何调整进给曲线是一个受到许多因素影响的问题。这给通过调整轨迹消除毛胚回弹造成的偏差带来很大困难。本文提出一种模型,将整个无模旋压系统看成一个线性黑箱,并作了对角线化处理。从中得出的算法是非常简单实用的。
Moldless spinning pressure forming parabolic antenna reflector is a complex mechanical process. The profile wheel is fed along a given plane curve controlled by a profiling numerical control device. The profile wheel is calendered on the blank surface to determine the final shape of the reflective surface. How to adjust the feed curve is a problem that is affected by many factors. This poses great difficulties for adjusting the trajectory to eliminate deviations caused by the rebound of the blanks. This paper presents a model that treats the entire moldless spinning system as a linear black box and diagonalizes it. The algorithm that comes out is very simple and practical.
