大口径环形天线反射器由于受到收拢高度及展开臂长度的限制,有时很难实现主、副索网构型上的完全对称设计,因而造成了反射器正、反向放置变形上的差异,为反射器型面调试带来了困难.提出一种非对称索网系统主、副网等刚度设计方法,通过该设计可以使得索网系统的正反向变形相等,实现反射器正反两种状态下的型面平均后等效在轨无重力型面的目的,为大口径环形天线地面调整和在轨型面预测提供了便利.
Large diameter loop antenna reflector due to the collapse of the height and the length of the deployment arm, sometimes difficult to achieve complete symmetry on the main and the secondary cable network design, resulting in the reflector is placed in the reverse, the difference is the deformation of the It is difficult to debug reflector surface.This paper presents a stiffness design method of main and sub-net of asymmetric cable net system, through which the positive and negative deformation of the cable net system can be equalized to realize the positive and negative state of the reflector The average of the lower profile is equivalent to that of the non-gravity profile of the orbit, which is convenient for the adjustment of the ground of the large aperture loop antenna and the prediction of the profile of the orbit.
