| 摘 要： | 采用结构拓扑优化方法,对动力总成悬置支架进行了优化.在最优拓扑结构的基础上进行结构修改后,一阶固有频率明显提高,而重量有所减小.从加强筋的优化结果来看,在平行于一阶弯曲振型方向上布置加强筋,可获得较好的效果.研究表明,在产品的概念设计阶段采用拓扑优化方法,能给产品的详细设计提供一个很好的基础.

| Abstract: | The power-train mount bracket has been researched by topological optimization method.Based on the optimal topological,structural modification has been implemented;and it makes the structure has higher first-order natural frequency and less weight.Through analyzing the optimal ribs topological,the conclusion could be drawn that it will gain better result to place the ribs paralleled with the first bending mode shape of the bracket.The research indicates that,in the concept design phase,topological optimization may provide a perfect base for the subsequent detailed design. |
