• 纵梁

  A topological optimization model and a simple optimization model was built based on solid elements. With the objection that the volume of the frame is minimal,the carling section dimensions was optimized and the results of optimization was analyzed.

  以实体单元为基础创建了车架结构的拓扑优化模型和简单的尺寸优化模型,以车架的纵梁截面尺寸为设计变量,以车架结构的总体积最小为优化目标,对车架纵梁的截面尺寸进行优化并分析了优化结果。
