Abstract

Abstract

The hot tension for hot forming part of AA5182 aluminum alloy are carried out at the strain rates of 0.0015s-1, 0.015s-1, 0.15s-1, and 1.5s-1, and the developed Johnson-cook constitutive model for the simulation of frontal impact is presented. The energy absorbing performance and mechanical properties for the vehicle body of hot forming part of AA5182 aluminum alloy are analyzed. The results show that the higher the flow stress and the lower the fractured strain of hot forming part of AA5182 aluminum alloy with the increasing of strain rate. The intrusion displacement of the hot forming 5182 aluminum alloy parts is appropriate for the satisfaction of vehicle body, there is a better energy absorbing performance and mechanical properties of hot forming part of AA5182 aluminum alloy for the vehicle body. Therefore the hot forming part of 5182 aluminum alloy can be applied to vehicle body design.
