Based on the design theory of ultrasonic transducer, the design and engineering calculation method of the high power ultrasonic transducer is proposed. The transducer consists of a longitudinal sandwich transducer, a halfwave vi-bration conical horn and a disk-rod shaped tool head. According to the design parameters and characteristics, an actual transducer has been developed. Through tests, the transducer frequency is f =20.24 kHz and the nominal power is up to 1500W. This result is consistent with the original design, and indicates that this calculation method is feasible. This transducer can be used for wastewater treatment, oil exploitation, biodiesel processing and so on.
