载人航天器光壳结构用胶接支座设计与强度分析
|
摘要
针对载人航天器密封舱的光壳结构,设计了一种变厚度的胶接支座,并对其胶接强度进行了仿真分析和试验验证,得出了胶接支座的承载能力,为在光壳结构上使用胶接的形式进行安装孔设计时提供了设计参考。
In view of the light shell structure of the manned spacecraft sealed cabin, a adhesive scaffold with variable thickness design is designed, and the bonding strength is simulated and tested. The bearing capacity of the adhesive scaffold is obtained, which provides a reference for the design of the installation hole in the form of the light shell structure.
