摘　　要：为结合镁的轻质高强与铝的耐腐蚀性,利用大型有限元软件ANSYS/AUTODYN对镁铝薄板的爆炸焊接过程进行了仿真模拟,得到其最佳工艺参数,即当基覆板间距为2 mm、装药高度为13 mm时,镁铝薄板具有良好的焊接效果。设置试验进行验证,试验结果与模拟结果具有良好的一致性,可见镁铝薄板具备爆炸焊接的可行性。In order to combine the light weight and high strength of magnesium with the corrosion resistance of aluminum, the large-scale finite element software ANSYS/AUTODYN was used to simulate the explosive welding process of magnesium-aluminum sheet. The best process parameters were obtained, that is, the spacing between substrate and fly plate is2 mm and the charging height is 13 mm. Under the best process parameters, the magnesium-aluminum sheet has a good welding effect. The test was set up for verification, and the test results were in good agreement with the simulation results. It can be seen that the explosive welding of magnesium-aluminum sheets has the feasibility.
