Vibration Transfer Optimization of Torpedo Based on Workbench Response Spectrum

For reducing structural vibration transfer response and optimizing design parameters in the scheme design phase of a torpedo, finite element analysis is employed to establish a parameterized equivalent model of torpedo structure based on Workbench. Response spectrum analysis is conducted for the shell of a certain type torpedo. The design parameters, like equivalent concentration of mass, shell thickness, and size of reinforcing rib with rectangular cross section, are optimized to reduce the vibration transfer response. Simulation results show that this parameterized equivalent model can effectively simulate the characteristic of structural vibration transfer of a torpedo, and the vibration transfer response of the homing head cabin decreases after optimization.
