摘要(Abstract)：

爆炸焊接过程中,焊接件界面温度的高低对焊接质量产生直接影响,因此爆炸焊接界面温度场是爆炸焊接理论研究的一个重要内容。通过对引起爆炸焊接界面温升的因素进行理论分析后,认为引起焊接界面温升的因素除了前人指出的基板和复板的冲击温升、畸形变形能温升之外,还应包括基板和复板之间的气体绝热压缩温升这三部分组成。其中基板和复板的冲击温升可由Hugoniot方程和自由电子气模型得出,畸形变形能引起的温升采用Johnson-Cook热黏塑性本构方程进行计算,气体绝热压缩引起的温升则通过气体的状态方程推导得出。
The temperature of the explosive welding interface affects welding quality directly in the process of explosive welding,so it is an important aspect of theoretic study on the explosive welding.Based on factors that cause the temperature ascending of the explosive welding interface were analyzed theoretically,the conclusion was drew that the temperature rising of the explosive welding interface also included adiabatic compression of gas besides shock temperature and abnormality deforming energy between the basic plate and fly plate.The shock temperature between the basic plate and fly plate could be calculated by Hugoniot equation and free-electron gas model,Johnson-Cook's thermal visco-plasticity constitutive equation was used to calculate the temperature rising caused by the abnormality deforming energy,and the temperature rising caused by adiabatic compression of gas could be deduced by gas equation of state.
