本文通过对爆炸焊接界面驻点附近应变率场的数值计算,按绝热塑性剪切概念,建立了界面温度的近似计算方法。同时通过数值计算确定了焊接参数窗口上限公式中的系数N的方法。
Based on the numerical calculation of the strain rate field around the explosive interface and the adiabatic plastic shear theory, an approximate calculation method of interface temperature is established. At the same time, the method of determining the coefficient N in the upper limit formula of the welding parameter window is determined by numerical calculation.
