基于压电超声的金属箔材固结振动系统能量建模

Energy Modeling of Metal Foil Consolidation Vibration System Based on Piezoelectric Ultrasonic

为完成对金属箔材超声固结过程的研究,探讨金属箔材超声固结机理,通过对金属箔材固结振动系统进行能量建模并进行运动学分析,从微观角度对金属箔材超声固结过程进行剖析。结果表明,在一定的压力和超声振动作用下,金属箔材间的高频振动摩擦会导致温度升高进而提高进入材料界面的能量,从而使金属原子间的扩散系数增加,金属箔材得到软化,最终金属相互键合形成界面固结。

In order to complete the research on the ultrasonic consolidation process of metal foil,the ultrasonic consolidation mechanism of metal foil is discussed.Through the energy modeling and kinematic analysis of the vibration system of metal foil consolidation,the ultrasonic consolidation process of metal foil is analyzed from a micro perspective.The results show that under a certain pressure and ultrasonic vibration,the high-frequency vibration friction between metal foils will lead to an increase in temperature and thus increase the energy entering the material interface,thereby increasing the diffusion coefficient between metal atoms,softening the metal foils,and finally bonding the metal to form an interface consolidation.
