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。
Aiming at the uncertainty of modal parameters in the solution of the acoustic vibration problem of solar array structure in high frequency, the statistical energy analysis parameters of sandwich structure of solar cell array panel are studied deeply from the view of statistical mode and energy balance. And power flow model creation method, and quickly get the sandwich structure of solar cell vibration response. The results of comparison and experiment show that the two methods are in good agreement with each other, which verifies the effectiveness of the acoustic vibration response analysis method for the structure of small satellite solar array and can be used as the dynamic analysis of solar array structure in the development of small satellite engineering Benefit supplement.
