Abstract: With an aim practical application of the vibration stress relief (VSR) technology,the evaluation methods of the VSR effectiveness stipulated in the JB/T5926-91 were compared and analyzed through the study of their evaluation principles and their application characters and scopes were given.Some up-to-date evaluation approaches under research were intvroduced,according to their principles,characters and application.In connection with atual engineering application,dynamic stress criterion(DSC) was emphatically introduced,which was compared with the Mathar method,a typical approach of the residual stress analysis.The result indicated that they had a similar accuracy and reliability.But the DSC has evaded the traditional problem,which the residual stress was measared in the site,and can evaluate the effectiveness while vibrating,which makes it easier to realize the automation of VSR process.
