The 3D Shape Optimal Design of Transformer Tank Shield by Using Parameterized Design Sensitivity Analysis

  • Published : 2002.11.14


A 3D shape optimization algorithm integrates the geometric parameterizationi 3D F.E. performance analysis, steepest descent method with design sensitivity and mesh relocation method. The design sensitivity of the surface nodal points is also systematically converted into that of the design variables for the application to parameterized optimization. The proposed algorithm is applied to the optimum design of tank shield model of transformer and the effectiveness is proved.
