Optimization of Structure Parameters for Hydraulic Energy Accumulated Torpedo Launching Device

Abstract:

For the low launching noise and without increasing atmospheric pressure in chamber, the hydraulic energy accumulated torpedo launching device has been highly regarded by all navies around the world. Mathematical mode of the launch course of the device has been built. Combined with the tactics and technique index, the structure parameters of the device have been optimized with genetic algorithm. As several parameters which were different in degree and range, normalization was applied to convert multi-objective optimization into single-object optimization, and penalty function method was used to deal with constraints. The optimization result shows that the optimized structure parameters not only meet the requirement of launching, but the dimension of the device is more compact to fit the narrow configuration of submarine and may provide references to the design of hydraulic energy accumulated torpedo launching device.
