| Abstract: | The vibration level difference evaluation method was used to analysis the problem of dynamic optimization design for the ship's stern structure in metal material.The structural dynamic optimum model was created and solved by multi-island genetic algorithm method.Numerical results showed that changing the thickness of the plating could improve the vibration characteristics of the ship's stern structure. |
