Application of Concurrent Subspace Design to Shape Design of Autonomous Underwater Vehicle

The optimization process of concurrent subspace design (CSD) algorithm is reviewed in details. The study is carried out in the framework of the shape design of autonomous underwater vehicle (AUV), and which is divided into two disciplines, i.e., low drag design and low noise design. A multiobjective, multidisciplinary design optimization (M&MDO) model of the shape design of AUV is developed. An optimization design example of a certain AUV is analyzed based on CSD method. And the same time the approach is applied to shape design of AUV for validation. Finally, comparisons with the present experimental data are made. The analytical result shows that the drag and noise of optimal shape are greatly improved, and the CSD method has some important implication for AUV design.
