摘要: |
针对A6N01铝合金材料的压弯成形工艺,研究了压弯成形过程中等效塑性应变、残余应力、厚度减薄等参数的变化规律。基于原始材料和成形件疲劳试验数据,采用三参数幂函数形式进行数据处理,拟合得到S-N曲线。通过对比不同状态材料的疲劳寿命,探究压弯成形对该材料的疲劳寿命的影响。 |

Abstract: |
According to bending forming process of A6N01 aluminum alloy, the rules of the equivalent plastic strain, residual stress and thickness thinning parameters were obtained by test and FEM. Based on the materials fatigue test data, the form of three parameters power function was used for processing data and fitting S-N curve. By comparing the different states of material fatigue life, the effect of bending forming on the fatigue life of the material was explored. |
