汽车悬架系统需要能承受来自路面反复冲击载荷,为了制造出符合设计目标的汽车悬架三角臂零件,选择合理的工艺路线实现零件成形,应用板料成形模拟软件Dynaform对QStE500TM材料的三角臂零件成形工艺进行动态数值模拟与计算,在模具制造前预估冲压成形过程中坯料厚度及应力等变化。后处理分析结果表明冲压成形结束后没有拉裂痕迹,整体材料变形处于可行区域,但局部边界有起皱风险,翻边局部区域厚度有明显变化,主应变、次应变、边界材料流动及应变矢量均处于合理范围;也验证了零件冲压成形工艺路线的可行性,对零件结构优化和加工制造提供了参考依据。
The automobile suspension system needs to withstand the repeated impact load from the road surface. In order to manufacture the triangle arm parts of automobile suspension that meet the design goals and select the reasonable process route to realize the part forming, the sheet forming simulation software Dynaform is used to simulate the triangular arm parts of QStE500TM material Forming process for dynamic numerical simulation and calculation of the die before the expected manufacturing process of blank thickness and stress changes in the blank. The results of post-processing analysis show that there is no rupture mark after stamping, and the overall material deformation is in the feasible region. However, there is a risk of wrinkling at the local boundary and significant changes in the thickness of the cuff region. The main strain, secondary strain, boundary material flow and strain vector Are in a reasonable range; also verified the feasibility of parts stamping process route, to optimize the structure of parts and manufacturing provides a reference.
