Abstract:The maximum size scale of a Thin-walled Cavity Structure (TSC) with A Large Aspect Ratio (TCSA) for ultra-precision optical instrument used in space station is more than 500. The TCSA should be strong enough, and at the same time, its mass should be lighter. Firstly, the characteristics of the thin-walled structure with ring-rib and longitudinal rib cavity were discussed, and the optimization design method of the rib structure was put forward based on the rib contribution theory. Secondly, the mathematical mod… Show more
