Abstract：

Many disadvantages such as large computing and low precision existed in the traditional design method of ultrasonic vibration system. It was analyzed static force, modal and harmonic response of the energy transduced, amplitude transformer and tool head by the finite element simulation software ANSYS Workbench. The positions of both the minimum and the maximum displacements and stresses and the values of frequency were obtained, and the irrational dimensions were revised and optimized. Finally, the size of the energy transducer and prestressing force were determined. The amplification coefficient of amplitude transformer is 2.36, and the impedance of amplitude transformer is 8 Ω. The amplification coefficient of the tool head is 1.27, and the maximum amplitude of end face of tool head is 5.5 μm. The designed ultrasonic vibration system is applied in the ultrasonic tensile and compression tests, and when the loading is 10 kN, the amplitude is 5.4 μm, which drops by 1.8% only.
