Abstract:In order to improve the effect of the high-frequency vibratory stress relief on eliminating residual stress, the optimization design of a high-frequency vibration energy amplifying device was carried out using the orthogonal experimental method combined with the finite element software ANSYS, by setting the amplitude amplifying factor and the evaluation factor of amplitude uniformity as objective function, and the structural dimension parameters as design variables. The experimental studies of the high-frequency vibratory stress relief on AISI 1045 steel quenched specimens were carried out to study the effectiveness of the high-frequency vibration energy amplifying device for the high-frequency vibratory stress relief. The results show that the output amplitude of the electromagnetic exciter can be obviously amplified by the high-frequency vibration energy amplifying device and the output amplitude of the high-frequency vibration energy amplifying device is relative uniformity, whose amplitude amplification factor can be up to 7.30 and the evaluation factor of amplitude uniformity can as low as 0.68. The effect of the high-frequency vibratory stress relief on eliminating residual stress can be obviously improved by the high-frequency vibration energy amplifying device. The use of the orthogonal experimental method combined with the finite element software ANSYS as a tool to reduce the simulation runs in the optimization design of the high-frequency vibration energy amplifying device can improve the design efficiency, which has definite value in engineering application.
