[Abstract]:In order to improve the effect of high frequency vibration aging to eliminate residual stress, a high frequency vibration energy magnifying device is designed. Using the orthogonal experiment method and the ANSYS finite element software, the amplitude magnification and the amplitude uniformity evaluation factor are taken as the objective function and the structure size parameter is the design variable, and the high frequency vibration energy magnifying device is optimized. The effect of high-frequency vibration aging on the residual stress of AISI 1045 steel quenched by high-frequency vibration aging is studied experimentally. The results show that the amplitude magnification of the high frequency vibration energy magnifying device can reach 7.30, the amplitude uniformity evaluation factor can be as low as 0.68, and the high frequency vibration energy magnifying device can be used. It is significant to amplify the output amplitude of the electromagnetic vibrator and to output the relative uniform amplitude. The application of the high frequency vibration energy magnifying device greatly improves the effect of eliminating the residual stress in the high-frequency vibration aging system, and the optimization design of the high frequency vibration energy magnifying device is carried out based on the orthogonal experiment method and the ANSYS finite element software. In order to reduce the number of design plans and improve the efficiency of design, it has the engineering application value.
