小卫星太阳电池阵结构声振响应分析研究

针对高频段太阳电池阵结构声振问题求解中的结构模态参数不确定性,文章从统计模态和能量平衡的角度出发,深入研究了复合材料面板太阳电池阵夹层结构的统计能量分析参数确定及功率流模型创建方法,并快速得到了太阳电池夹层结构的声振响应。对比分析与试验结果,发现二者吻合很好,因而验证了该声振响应分析方法用于小卫星太阳电池阵结构的有效性,并可作为小卫星工程研制中太阳电池阵结构动力学分析的有益补充。

Structural vibro-acoustic response analysis of small satellite solar array

In view of the modal parameter uncertainty in a high frequency vibro-acoustic problem, the statistical energy analysis parameters are determined and the power flow model is constructed for the solar array sandwich panel with composite face sheets based on the statistic modes and the energy equilibrium. The vibro-acoustic response of the solar array sandwich structure is further obtained, and the analytical results agree well with the test data, which indicates that the vibro-acoustic analysis method is reliable and can be applied to the small satellite engineering. The vibro-acoustic analysis method can also provide a good tool for the dynamics analysis in the small satellite solar array structure development.
