- W4296492968 abstract "In this paper, the deployment mechanism of the spaceborne umbrella deployable antenna is taken as the research object. The working principle of the deployment mechanism is introduced, and the equation of motion of the deployment mechanism is obtained by using the analytical method. Combined with the structural parameters of the moving parts of the antenna deployment mechanism, the motion law of the key parts of the deployment mechanism in the process of antenna deployment is obtained. Through the force analysis of the deployment mechanism, the structure optimization model of the deployment mechanism is established, which takes the structural parameters of the deployment mechanism as the design variables and the minimum driving force as the objective. Through the ergodic method, the optimized structural parameters of the deployment mechanism are obtained. The maximum driving force of the optimized deployment mechanism is 30% lower than that before optimization, and the optimization effect is remarkable." @default.
