Hydrodynamic Optimization for the Shape of the Appendage Set of Submarine

以SUBOFF潜艇为母型,对导弹包进行参数化,基于CFD技术与iSIGHT优化平台,运用试验设计方法创建计算样本,引入响应面技术构造潜体总阻力与导弹包参变量之间的近似函数,并在此基础上采用现代优化算法以总阻力最小为优化目标寻优,确定最优点设计参数,分析阻力随各设计参数变化的规律。

A parametric missile dome was set for the SUBOFF submarine. Based on CFD and iSIGHT optimization platform, DOE （ design of experiment） was used to design the sample points for computation, and the technology of response surface model was integrated so as to build the approximating function between the total drag of the submarine and the parameters of the missile dome. The modem optimization technology was used to find the parameters which make the drag least. In the end, how the parameters affect the drag was analyzed briefly.
