Vibration modes and the sound field in an ultrasonic cleaning tank of tubular vibrator are calculated and analyzed with the finite element software ANSYS . The sound field distribution of the tubular vibrator is recorded by means of aluminum foil erosion .

利用有限元分析软件ANSYS，对 管形振子的振动模态及在清洗槽中的辐射声场进行数值计算分析，并用铝箔腐蚀的方法记录了管形振子的 声场分布情况。
