| Abstract: | To ensure the reliable on orbit operation of a large deployable truss antenna on satellite, the model is built and analyzed by finite element method; the temperature field distribution at different orbital positions is calculated by I deas; the calculated temperature is applied as a thermal load for the structural analysis, and the root mean square error of the reflective surface of the antenna at different orbital positions is calculated, and the temperature field and thermal deformation are analyzed under the space environment. The method can provide some references for the structure design and thermal control of satellite antennas. |
