基于iSIGHT优化设计平台，结合有限元分析软件MSC.Patran/Nastran对某深海载人平台总装台架进行重量优化。优化过程采用自适应模拟退火算法（ASA），在满足结构屈服强度的前提下，给出重量最小的优化方案。结果表明，优化方案满足结构屈服强度要求，且重量较原有方案明显减少。该方法可以推广到其他结构位置的优化设计中，对深海载人平台的进一步设计具有一定的参考价值。
Based on the iSIGHT optimization design platform, combined with the finite element analysis software MSC.Patran/Nastran, the weight of a deep-sea manned platform assembly bench was optimized. The optimization process adopts adaptive simulated annealing method (ASA), and on the premise of satisfying the yield strength of the structure, the optimization scheme with the smallest weight is given. The results show that the optimized scheme meets the structural yield strength requirements, and the weight is significantly reduced compared to the original scheme. This method can be extended to the design of other structural locations and has certain reference value for the further design of deep-sea manned platform.
