Method for Improving Sound Field Distribution of High- power Ultrasonic Cleaning

Based on the superimposing theory of sound wave and the standing wave characteristic of forming in clean basin, the transducers are distributed on two opposite faces of clean basin with radiation each other and the distance of radiation is maintained integer times of quarter wavelengths. It's acoustic field distribution in the directions of depth and horizontal has been studied by experiment and recorded on copperplate by means of aqueous solution of blue dye with ultrasonic radiation in highpower scale. The results show that compared with the radiation of clean basin base,the acoustic field uniformity in direction of horizontal and depth are well improved by this method.
