摘　　要：利用MSC.Marc大型通用软件研究了热循环条件下太阳电池板单元结构热应力分布及演变规律。结果表明:被粘接层正应力极大值位于结构中点,极小值出现在结构两端;胶层剪切应力极大值位于结构两端,极小值出现在中点;聚酰亚胺薄膜层取得太阳电池板单元结构最大正应力,粘接聚酰亚胺薄膜与碳纤维复合材料的硅橡胶层取得结构最大剪切应力;结构在低温保温阶段的最大正应力及最大剪切应力远大于高温保温阶段的最大应力;太阳电池板单元结构的最大应力值随热循环次数的增加而增加。The stress and strain distribution of elemental solar PV module structure-after thermal cycles were analyzed using MSC. Marc common software. The results showed that the maximal normal stress of bonded layer occurred in midpoint of structure, the least normal stress in the two ends of structure; The maximal shear stress occurred in the two ends of structure, least shear stress occurred in the midpoint; The maximal normal stress of elemental structure occurred in polyimide film. The maximal shear stress of elemental structure occurred in silicone rubber between polyimide film and carbon-fiber composite; The maximal normal and shear stress of the structure in low temperature is far larger than maximal stress in high temperature; Both the maximum of the normal stress and the shear stress in elemental structure increased with the increase of thermal cycles.
