| 摘 要： | 以纵向拉索调整力大小和可调整的纵向拉索数目为设计变量,可调整的纵向拉索数目最少和网状反射面的均方根误差最小为目标函数,应力和频率为约束条件,建立了大型空间网状可展开天线的形面调整的多目标优化数学模型,并用遗传算法进行了优化求解。优化结果表明:该方法在提高天线表面精度的同时,能有效地减少可调整的纵向拉索数目,降低了工程人员在网面调整中的繁杂劳动。并且,网面调整的总次数也远少于实际工程中的调整,对工程应用具有一定的指导意义。

| Abstract: | Multi-objective optimization model of large space net-shape deployable antenna was established.Regarded the adjusting force and adjustable cable number as the design variables,the minimum adjustable vertical cables and RMS of reflector as objective functions respectively,the stress and frequency as constraints,the optimization of shape adjustment with Genetic algorithm was performed.The optimum result indicates that the adjustable vertical cable number and onerous engineer labor are effectively decreased during shape adjustment,while the accuracy of net-shape surface is improved via the optimization adjustment method with relatively fewer adjust-ment times. |

| Keywords: | deployable antenna root mean square genetic algorithm shape adjustment. |
