| Abstract: | The broaching principle and the equipment of ultrasonic waveguide used for the processing of inner surface of waveguide were discussed.Piezoceramics transducer was designed with the ultrasonic wave generator which had automatic tracking systems of frequency.The piezoceramics transducer can be used in the broaching of ultrasonic waveguide.The calculation formula of the resonance frequency,nodal displacement,amplification multiple for amplitude lever were given.The characteristic of conductance-susceptance of acoustics system and the process of ultrasonic broaching were studied. |
