| Abstract: |
| According to characteristic of hydroforming of parallel multi-branch tubes, multi-objective problems were transformed to single objective problem of relational grade comparison by grey system theory. Two different objectives were selected, according to the principle that process parameters were optimal which of grey relational grade were maximum, the optimal loading parameters under different objective condition were obtained, and loading paths were optimized. The results indicated that parallel multi-branch tubes hydroformed under loading paths optimized by grey system theory could meet with the requirement that objective was optimal. And the optimal loading paths under different objectives were different, and the appropriate objective should be selected according to forming characteristic. |
