Collaborative Optimization and Its Application to Multidisciplinary Design Optimization of Torpedo General Design

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.
