| Abstract: | Based on reliability theory, combined with finite element method for structure optimization, the lightweight design for the lower ann of a suspension is conducted. After lightweight design, the mass of structure is reduced slightly and its reliability is improved greatly, attaining the goal of structure optimization. The application of optimized structure to prototype vehicle verifies the correctness of finite element analysis and the feasibility of the op-timization method. |
| Keywords: | reliability structure optimization lightweight FEM |
