Abstract This paper describes the application of the finite element method to simulation of an ultrasonic cleaning tank which consists of a liquid bath with vibrating plate walls. the vibration of a plate, from which the ultrasonic radiation takes place, is analyzed without loading, and it is shown that the location where the erosion occurs corresponds to the region of maximum stress in plate bending. Sound pressure distribution in the liquid bath, which is surrounded by the vibrating plate walls, is then considered as a two‐dimensional model in which the coupling between the plate vibration and the sound pressure in the liquid is taken into account. Some numerical demonstrations are made, which is compared with the measured results. the technique has again proved to be a useful means of solving problems of this kind.
