汽车辅助拉手结构设计研究

Structure Analysis Study on Automobile GAM Handle

对汽车辅助拉手改型设计方法的可行性进行研究。针对成型工艺产生缺陷的原因,在强度大的位置增加孔的尺寸,建立辅助拉手的有限元模型,分工况讨论各种载荷对辅助拉手的影响,对比了改型前后辅助拉手的强度变化。研究表明该改型设计方法在不影响产品强度的前提下,有效减小了因工艺产生的缺陷,同时也减少了材料的使用。

Feasibility of automobile handle retrofit program was researched. Dimensions of holes on the intensity position were increased because of process defects. The FEA model of handle was created. Various load cases influence on handle were studied. The handles before and after modification was compared. Research showed that the retrofit design method can effectively reduce defects by the process, costs, and had little influence on the impact strength.
