摘要：

A method for modal vibration control of elastic systems using additional vibrators called “wave-trapped horns” is proposed. Experimental verification of the method has been done for many large ultrasonic tools whose shapes are often adopted in ultrasonic plastic welding. Uniform amplitude distributions have been realized at the radiating faces of the tools. Effects of both the thickness and the number of the horns have also been investigated, with bending vibration of the horns found to diminish the effectiveness of the method. The validity of the method is finally confirmed under certain conditions. © 1990, Acoustical Society of America. All rights reserved.
