本文讨论了双环可展开索网天线的预紧优化。采用PSO（粒子群优化）并结合TS（禁忌搜索）来获得最优预张力。此外，将所有索网段的优化预紧力分为不同的组，以满足工程应用。最后，为了验证本文算法的最优解，制作了比例模型并进行了相关精度测试，说明改进的PSO对于索网天线预紧优化是有意义的。
This paper addresses the pretension optimization of a double-ring deployable cable net antenna. PSO (particle swarm optimization) is employed and combined with TS (Taboo search) to obtain the optimal pretension. In addition, the optimized pretension of all cable net segments is divided into different groups to satisfy engineering applications. Finally, to verify the optimal solutions with the algorithm investigated in this paper, a scaled model was manufactured and relevant precision tests were taken, which illustrate that the improved PSO makes sense for the pretension optimization of cable net antennas.
