Cavitation is a common failure form of hydraulic machinery.Ultrasonic cavitation erosion experimental device is com-monly used to study the cavitation process and the cavitation resistance of materials.According to the principle of ultrasonic cavita-tion and the requirements of ultrasonic cavitation erosion experimental device,a conical compound horn is designed by using the wave equation and the design theory of traditional horn.Modal analysis and harmonic response analysis of the horn are carried out by ANSYS software,and the multi-size structure optimization design is carried out to obtain the optimal size parameters.Based on the optimized parameters,the conical composite horn is developed,which is connected with the transducer and the tool head to form the ultrasonic resonance system,and the impedance analysis and vibration performance test are carried out.the results show that the vibration effect of the horn is good and meets the requirements of ultrasonic cavitation erosion experimental device.
