摘要
为了研究过渡层(1060Al)对于钛/铝复合板爆炸焊接的影响,以爆炸焊接理论为基础,在 ANSYS/LS-DYNA 软件中分别对 TA2/5083Al 与 TA2/1060Al/5083Al(0.3/0.5 mm 过渡层)复合板爆炸焊接进行数值仿真,并对比两组模型的位移变化、速度变化、压力变化.研究表明,在1.4 cm布药厚度情况下,在TA2与5083之间设置1060Al,可以使碰撞速度和碰撞压力的峰值得到显著下降,使基复板更加平稳地结合,获得较好的爆炸焊接复合板.
Abstract
In order to study the effect of transition layer(1060Al)on explosive welding of titanium/aluminum composite plates,numerical simulations were conducted on TA2/5083Al and TA2/1060Al/5083Al(0.3/0.5mm transition layer)composite plates in ANSYS/LS-DYNA software based on the theory of explosive welding.The dis-placement,velocity,and pressure changes of the two models were also analyzed.Research has shown that inserting 1060Al between TA2 and 5083 at a thickness of 1.4cm can significantly reduce the peak values of collision velocity and collision pressure,resulting in a smoother bonding of the base composite plate and better explosive welding com-posite plate.
