Dynamic Analysis and Parametric Optimization of Telescopic Tubular Mast Applied on Solar Sail

Abstract Large-scale solar sails can provide power to spacecraft for deep space exploration. A new type of telescopic tubular mast (TTM) driven by a bistable carbon fiber-reinforced polymer tube was designed in this study solve the problem contact between sail membrane and under light pressure. Compared with traditional TTM, it has small size, weight, high extension ratio, simple structure. The anti-blossoming self-unlocking structure proposed TTM described. We aimed simplify complex into beam model equal linear mass density, simulation results showed good consistency. dynamic equation derived based on equivalent model, effects different factors vibration characteristics were analyzed. performance parameters optimized multiobjective genetic algorithm, prototype production load experiments conducted. show that advantages complete deployment large-scale sails, which is valuable future
