摘要
以爆炸焊接理论为基础,采用数值模拟方法,在软件ANSYS/LS-DYNA上模拟AZ31B镁合金和5052铝合金的爆炸焊接过程,并与实验结果进行对比。结果表明:爆炸焊接过程中能量是以波的形式进行规律传递,爆炸时覆板与炸药的接触面最大的等效应力可以达到1.802 GPa。通过SEM对结合面进行微观观察,可以看出数值模拟结果与实验结果一致性较好。所得结果可以为爆炸焊接成型制备镁/铝双层复合板及其连接界面结合机理的研究提供理论支撑。
Based on the theory of explosive welding, the numerical simulation was used to simulate the explosion welding process of AZ31B magnesium alloy and 5052 aluminum alloy by using software ANSYS/LS-DYNA. The simulated result was compared with test result.The results show that the energy in the process of explosion welding is transmitted in the form of wave. The maximum equivalent stress of the contact surface between the superstrate and the explosive during the explosion can reach 1.802 GPa. Microscopic observation of the bonding surface by SEM was carried out, it shows that the numerical simulation results are in good agreement with the experimental results. The obtained results can provide theoretical support for the study of the preparation of magnesium/aluminum double-layer composite sheet and bonding interface by explosive welding.
