摘要

摘要: 在进行星表天线地面真空热环境试验过程中,传统的红外加热设备会造成测量光路遮挡、降温速率减慢等影响。为提高试验准确性,提出了基于天线旋转受照的真空热试验方法。利用虚拟热试验平台对旋转受照状态下天线温度场进行仿真分析,得到天线温度场的分布与变化,并与试验数据对比,验证了仿真建模的准确性和试验方法的可行性。

Abstract: In the thermal vacuum test on the ground, the traditional infrared heating array often affects the deformation measurement. For example, the belt may hinder the working of antenna, and then affect the temperature gradient. In order to improve the accuracy of tests, a new method is proposed for the antenna's thermal vacuum test, that is to keep the antenna in a rotation state in the thermal vacuum environment. The temperature field distribution of the antenna is obtained by the virtual thermal vacuum test platform, which is verified by the further experimentation. Compared with the test data, the simulation results are reliable.
