摘　　要：结合最大1阶频率为目标和最小柔度为目标的拓扑优化技术,实现了1种汽车发动机支架的轻量化设计。新设计的支架在满足强度和频率要求的基础上,质量比原支架减少了48.5%,同时进行了强度和模态试验,验证了有限元方法的准确性。The topological optimization technology combined the objective of largest first order frequency and the objective of smallest compliance,realized the lightweight design of one automobile engine mount. On the premise of satisfying the intensity and frequency,the new mount mass decreased by 48. 5% than the original. The intensity and modal test had been completed,the accuracy of the finite element method was verified.
