摘要

在卫星发射过程中星载天线要经受复杂的动力学环境。针对某光学卫星由于对地板相机尺寸大导致数传天线安装空间不足及视场遮挡的问题,提出了一种新的对地数传天线结构设计方案。通过动力学仿真对天线结构的刚度和动强度进行了分析及优化。对优化后的天线结构进行了动力学环境试验。试验结果表明,天线结构满足刚度和强度抗力学指标要求,天线能够适应卫星发射对天线动力学载荷的要求。

Abstract

Satellite antenna suffers complex dynamic environment during satellite launch. A new type of structure design of antenna used for data transmission was proposed, aiming at the problem of insufficient antenna installation space and view shade, because of big size of the optical camera. The structure dynamic characteristic of antenna was analyzed and optimized, and also the dynamic environment test was carried out. The results show that: the structure design of antenna meets the stiffness and strength requirements of satellite launch.
