摘　　要：为改善铝-钢爆炸焊接复合板的结合质量,以T2纯铜作为中间层、Q235钢作为基板、1060铝作为复板进行了爆炸焊接试验,通过金相显微镜观察复合板界面形貌并通过拉伸试验测试其力学性能;采用ANSYS/AUTODYN软件对爆炸焊接过程进行数值模拟。试验结果表明:1060-T2与T2-Q235界面均呈波状结合;T2铜中间层的引入减少了复合板结合界面的孔洞、裂纹等微观缺陷;1060-T2-Q235爆炸焊接系统的复板动能利用率较1060-Q235系统提高了3.01%;1060-T2-Q235复合板抗拉强度为319.2MPa,满足抗拉强度要求。数值模拟结果与试验结果具有较好的一致性。In order to improve the bonding quality of aluminum-steel explosive welding composite plate,the explosion welding test was carried out with T2 pure copper as the intermediate layer,Q235 steel as the substrate and 1060 aluminum as the clad plate.The interface morphology of the composite plate was observed by metallographic microscope and its mechanical properties were tested by tensile test.ANSYS/AUTODYN software was used to simulate the explosive welding process.The test results show that 1060-T2 and T2-Q235 are waveform combination;Copper interlayer reduces the micro defects such as holes and cracks at the bonding interface of the composite plate.The kinetic energy utilization rate of 1060-T2-Q235 explosive welding system is 3.01%higher than that of 1060-Q235 system;The tensile strength of 1060-T2-Q235 composite plate is 319.2MPa,which meets the tensile strength standard.The numerical simulation results are in good agreement with the test results.
