The necessity of vibratory stress relieving:

The relaxation and redistribution of residual stress in the part will cause deformation of the part. In order to stabilize the size of castings and welded parts, the basic methods are: 1. Reduce the value of the original residual stress. 2. Improve the uniformity of the material structure and performance and make the stress distribution uniform, so that the relaxation coefficient ratio tends to 1.3. Reduce The absolute value of the residual stress relaxation, in other words, increases the relaxation stiffness.

A large number of tests and practical examples at home and abroad have proved that vibratory stress relief has a good effect on stabilizing the dimensional accuracy of parts. Its function is not only reflected in the small amount of dimensional accuracy change during long-term use, but also can stabilize the size of the part in a relatively short period of time.
