An Optimization Method of Torpedo Performance Based on Trajectory Simulation

General performance optimization based on simulation is a new approach for overall design of complex elec-tromechanical product. The overall design of a torpedo involves many disciplines and a large number of parameters. To improve torpedo′s hitting effect, it is necessary to reasonably match theses parameters. In this paper, a method based on trajectory simulation is proposed to optimize general performance of a torpedo, a complete trajectory model is built, and a trajectory simulation library is compiled. Furthermore, an optimum matching simulation is conducted by employing genetic algorithm for some key parameters of trajectory design. The result indicates that the proposed performance optimization method is effective, and can be applied to other parameters of torpedo general performance.
