| Abstract: | This paper focuses on the preform die shapes optimization through controlling forging geometry by using sensitivity analysis based finite element method. When lower die velocity equals to zero, the sensitivity boundary conditions also equal to zero and preform die shape keeps constantly in optimization iteration. In order to overcome the above limitation, a method dealing with sensitivity boundary conditions is put forward. Using this method, both upper and lower preform die shapes can be optimized simultaneously. Finally, an optimization design example is given to demonstrate the reliability of this method. |
