| 摘 要： | 空间站大型柔性太阳翼系统在轨运行期间会受到周期性的热辐射作用,导致结构温度周期性变化,从而诱发太阳翼的振动。为研究太阳翼桅杆热控涂层特性对热诱发振动的影响,文章采用热-结构顺序耦合的方法,对桅杆无涂层、电镀涂层和白漆涂层3种不同表面状态进行热诱发振动分析,得到了太阳翼的位移-时间响应结果。对比不同涂层下太阳翼参考点的振动结果可以看出:涂层特性对于热诱发振动是有影响的,其中白漆涂层能大幅度减小振动的振幅。

| Abstract: | On the orbit, a large flexible solar wing system of the space station would suffer a periodic thermal radiation and therefore a structural vibration. In order to investigate the influence of the mast''s thermal control coating on the vibration, a sequential coupled thermal-structural analysis method is used to calculate the thermally induced vibration. For three different states of the mast''s surface, that is, without coating, with electrodeposited coating and and with white paint coating, the displacement vs. time response is calculated correspondingly. The results show that the thermal control coating indeed has an influence on the thermally induced vibration, and the greatest mitigation effect is found for the case with the white paint coating. |
