摘要
根据声学理论阐明了声阻抗的物理意义并给出了它的数学表达式。根据弹性力学的理论阐明了应力波在两种不同介质界面上的反射和透射。在此基础上分析了声阻抗对钛-钢复合板在爆炸焊接过程中的意义和作用。
According to the acoustic theory, the physical meaning of acoustic impedance was illuminated, and the mathematical expression was given. Reflection and transmission of stress wave on two different interfaces was clarified according to the elasticity theory. Meaning and function for acoustic impedance in explosive welding process of the titanium-steel composite plate was analyzed based on those.
