摘要: 基于响应面的协作优化算法，结合鱼雷总体设计的实际特点,将鱼雷总体设计划分为9个学科，分析了各学科间的耦合因素，建立了鱼雷总体设计多学科设计优化的统一模型和基于协作优化算法的数学模型，并进行了实例验证，结果表明，基于响应面的协作优化算法很好地解决了鱼雷总体设计多学科设计优化中学科间耦合关系的复杂问题，收敛速度快，可靠性高。采用该方法能够提高鱼雷设计质量，避免人力和物力浪费，降低设计风险。Abstract: Based on the response surface approximation collaborative optimization (RSACO) , an effective method for complex systems design, we divided the general design of torpedo into nine disciplines such as shape design, structure design, trajectory design, etc. The coupling connection among disciplines was discussed, and a multidisciplinary design optimization (MDO) mathematic model based on RSACO of torpedo general design was established. The results of an example of torpedo general design demonstrate that RSACO is a fast and efficient method to solve the complicated coupling relations in MDO of torpedo general design. The proposed method can improve the torpedo quality, avoid the waste of resources and reduce the design risk.
