Abstract
The present invention discloses a method of constructing a high-frequency vibratory stress relief device for eliminating residual stress of a small work-piece. The method comprises the following steps: fabricating a high-frequency vibration energy amplification device; fabricating a clamping device; mounting the high-frequency vibration energy amplification device; obtaining surface residual stress distribution on the small work-piece by means of X-ray diffraction; establishing a finite element model of the small work-piece; determining a target frequency f, determining the structural dimensions of the high-frequency vibration energy amplification device; analyzing the displacement mode to obtain loci of the vibration node lines and number of the vibration node lines; clamping the small work-piece; attaching strain gauges; connecting all devices. The present invention has the advantage of being able to increase the vibration energy acting on the small work-piece to achieve a better effect of high-frequency vibratory stress relief.
