摘要
为满足汽车座椅轻量化和安全性的需求,综合采用轻量化材料和结构拓扑优化设计技术,提出了一种碳纤维复合材料乘用车座椅设计方法.新型座椅骨架由碳纤维层合板外壳和短切碳纤维加强筋两部分组成.首先,为提高座椅结构刚度和稳定性,利用结构拓扑优化技术在碳纤维层合板外壳区域内布置合理的加强筋,然后,通过优化碳纤维层合板外壳,提高结构整体刚度,降低骨架质量.结果表明,与参考钢制骨架相比,新型座椅骨架不仅整体刚度得到大幅提升,而且质量减少了30.72%,有显著的轻量化效果.
In order to meet the demand of lightweight and safety of the automotive seat,a design method for the carbon fiber composite material passenger car seat was proposed by using lightweight material and structural topology design optimization technology. The suggested new seat frame was composed of two parts, namely the carbon fiber laminate and short carbon fiber stiffener. In order to improve the stiffness and stability of the seat frame, the topology optimization method was used to arrange the layout of the stiffeners on the shell of carbon fiber laminate, and then the composite laminate optimization was implemented to improve the overall stiffness of the structure and reduce the weight of the frame. The results show that not only the overall stiffness of the new seat is raised,but also a significant reduction in weight about 30.72% is achieved.
