使用5052铝合金材料加工成标准的材料拉伸试样,然后按照铝合金拉伸国家标准的要求,对加工好的试样分别进行不同应变速率下的拉伸试验,得到5052铝合金的应力应变曲线,为铝合金底盘车架的有限元建模提供材料本构模型参数。
The 5052 aluminum alloy material is used to process the standard material tensile specimens, and then in accordance with the requirements of the aluminum alloy tensile national standard, the processed specimens are subjected to tensile tests at different strain rates to obtain the 5052 aluminum alloy The stress-strain curve provides material constitutive model parameters for the finite element modeling of the aluminum alloy chassis frame.
