Abstract

The necessity is verified analytically and experimentally of the two-dimensional vibration analysis for the high-intensity ultrasonic system with a large diameter. By the joint use of the modal analysis with the finite element method, the two-dimensional vibration analysis program is made so as to be able to deal with the vibrational and piezoelectric behaviours of a body. On the basis of the respective results analyzed and measured by means of the program and the time-average holography, the followings are obtained : (1) The analyzed values coincide with the measured values. (2) The ultrasonic system with a large diameter must be analyzed by the two-dimensional vibration analysis method. (3) The program can be applied to analysis and design of the ultrasonic system.
