Song Dynasty.> As we all know, any ultrasonic welding, whether it is ultrasonic plastic welding or ultrasonic metal welding, can be described by four parameters. In other words, the effect of ultrasonic welding only depends on four parameters, namely frequency, time, pressure and amplitude. The first three parameters are very convenient to control, adjust and display. Equipment manufacturers and equipment users know them well and pay enough attention to them. They are also adjustment parameters in the daily operation of the equipment. The amplitude (displacement) of ultrasonic vibration is a key indicator of ultrasonic equipment, and it is also the most difficult physical quantity to measure and understand. Except for experts and scholars, not to mention equipment users, even most equipment manufacturers do not care much about it. We have counted most of the operating instructions for ultrasonic random equipment, and there are few instructions on ultrasonic amplitude, including the physical meaning of amplitude, the control and adjustment of amplitude, and the relationship between amplitude and welding quality.

.> For ultrasonic vibration systems, from the perspective of energy transmission, the main indicator is called the sound intensity of the ultrasonic wave. It refers to the energy transferred per square centimeter per second in the direction perpendicular to the propagation direction of the traveling wave, that is, =/&&& where: &r is the density of the material, C is the speed of ultrasonic wave propagation in the material, is the angular frequency, is the amplitude of the ultrasonic wave, obviously, ultrasonic wave As the amplitude increases, the ultrasonic energy increases exponentially with the square relationship.
