| 英文摘要: |
| Vibration stress relief (VSR) technology has become the standard technology to reduce the residual stress of the components, which shows the advantages of low energy consumption, low cost, high efficiency and so on. In this paper, the macro and micro mechanisms of vibration stress relief technology are introduced. Review and technical features of harmonic frequency spectrum VSR, high frequency VSR and ultrasonic VSR are presented. Evaluation of the effect of VSR via nondestructive method is introduced. The development of VSR is summarized, and the future development trend and research direction are put forward. |
