| 摘 要： | 本文探讨了在天象三球仪研制中,运用计算机优化,并针对此问题,对约束优化的复合形法作了两步新尝试,较好地解决了初始可行点的确定问题,改造了迭代方法,从而使收敛速度明显加快。此外,提出了据优化结果进行二次优化的方法,使最终结果,既满足设计目标,又方便制造。

| Abstract: | In this paper application of computer optimization in research and manufacture of three -sphere orrery is dismissed ,and introduced two concepts for restrained optimality of conpound shapes. Initial values of two vertexes are chosen , which results more better acceptable values than by other means. Improve the iterative calculation method for compound shapes , so accelerates the Convergence evidently.Besides,according to design requirements for the three-sphere orrery double optimization on primiaty optim zatlcal result is inducted, so the final result not only satisfies the design but also gives Convenience for manufacture. |
