Control of vibroacoustical load and time of pressurevessel by vibroacoustics ageing;

Research on the vibratory stress relief used to reduce butt weld residual stress of dissimilar steel;

The mechanism for vibratory stress relief of stainless steel;

Application of vibratory stress relief to the residual stress elimination for steel manifords;

Investigation on vibration stress relief of post-welded drums;

To quickly and quantitatively evaluate the vibration stress relief (VSR) effect in the site, assumption about VSR criterion is presented.

The Research for the Vibration Aging of the Large Mill Vessel;

Based on the analysis of the effect of excitation force of vibration aging on the fatigue life of white cast iron parts, the selection gist for excitation force was determined.

This paper introduced the damage of residual stress to machine building,analyzed the theory and application of vibration aging as well as its effect on eliminating residual stress.

Development of magnetostrictive vibration ageing device

The means of eliminating stress by vibration ageing has already been applied muchabroad, but not so popularized at home and with little effect.

Workpiece internal stress s existence light causes the workpiece to distort, sometime, it will reduce the workpiece the fatigue life to cause accident, but through the vibration ageing technology s application, solved workpiece internal stress question, eliminate perman.
