| 目的 解决热轧酸洗复相钢CP800在底盘拖曳臂外壳零件应用过程中出现的开裂问题。方法 借助有限元软件AUTOFORM对零件进行仿真评估，研究材料性能、润滑状态、模具圆角、坯料尺寸等对开裂的影响，分析影响开裂的原因。结果 通过提升材料性能、降低摩擦因数、放大凹模圆角以及优化坯料边界，可以有效改善开裂区域的成形性能，其中优化坯料边界效果最佳，开裂风险可完全消除。结论 材料性能按均匀伸长率≥5%控制，同时通过优化开裂区域坯料边界及放大凹模圆角，开裂得到了有效解决。 |

| The paper aims to solve the cracking problem of hot rolled pickling dual phase steel CP800 in the application of chassis drag arm shell parts. Based on the simulation assessment with AUTOFORM software, the effects of material properties, lubrication state, die fillet and blank size on cracking were studied, and the causes of cracking were analyzed. By improving material properties, reducing friction coefficient, enlarging die fillet and optimizing blank boundary, the formability of the cracked area was be effectively improved. Among them, optimizing blank boundary had the best effect and cracking risk can be completely eliminated. The uniform elongation of the material is controlled by 5%. By optimizing the blank boundary of the cracking area and enlarging die fillet, the cracking is effectively solved. |
