| Abstract: | A multidisciplinary optimization model was established based on structural stress method,which considered comprehensively both weld fatigue life and structural deformation as constraint conditions.Numerical results show that the multidisciplinary constraints optimization design of welding structure can be realized by using the proposed method meeting both the life and deformation constraints. |

| Keywords: | welding structures fatigue life structural stress method optimization design |
