| description | The relaxation and jumping from slot of the power rope of the antenna deployment mechanism are likely to occur in the process of antenna deployment and folding. The deployment mechanism of the high precision satellite umbrella antenna is taken as the research object, and the working principle of the antenna deployment mechanism is analyzed. The equation of motion of the deployment mechanism is obtained by analytical method. Combined with the structural parameters of the parts of the antenna deployment mechanism, the relaxation law of the power rope of the deployment mechanism is obtained. Taking the structural parameters of the deployment mechanism as the design variable and minimum relaxation of the power rope as the goal, the structure optimization model of the deployment mechanism is obtained. The structural parameters of the optimized deployment mechanism are obtained by simulated annealing algorithm. The relaxation and receiving functions of the antenna deployment mechanism before and after optimization are performed with experiment, and the relaxation variable of the power rope is tested when the mechanism is working. The results show that the relaxation variable of the power rope of the optimized deployment mechanism is reduced by 90% compared with that before optimization, and the optimization effect is remarkable. |
