Abstract
This paper proposes a method to analyze numerically the excited modes for a cleaning tub model of small size. The vibration mode is caused by vibration of the cleaning tub that concentrates on the surfaces of tub walls connected with the surfaces of the water. This mode does not contribute to cleaning directly. On the other hand, the sound mode (named E mode) is the state that large sound pressure can be observed at most areas of the cleaning tub. The distribution of E mode is ovoid. The resonance frequency of E mode depends on the size of the cleaning tub, the thickness of the tub walls and the material of tub walls. We have also investigated the influence when the driving vibrator put to the bottom of the cleaning tub is working. It has been found as to E111 mode that the sound mode nearby the bottom approaches to the sound mode when the bottom is rigid body.
