Summary of the influence of JH vibration aging equipment on the workpiece

Effect of JH vibration aging equipment on residual stress
The residual stress inside the part is the main reason for its dimensional accuracy. It is not only the magnitude of the residual stress that affects the stability, but also the uniformity of the stress distribution. JH vibration aging equipment has a good effect on reducing and homogenizing residual stress, and the residual stress elimination rate is 30%-80%.
The influence of JH vibration aging equipment on deformation resistance The deformation of the part depends not only on the magnitude and distribution of residual stress, but also on the relaxation stiffness and deformation resistance. JH vibration aging equipment not only can reduce and homogenize residual stress, but also improve the material's resistance to deformation, that is, improve the elastic properties of the material.
Effect of JH vibration aging equipment on fatigue life Vibration aging treatment mainly aims to eliminate the influence of residual stress on fatigue life. JH vibration aging equipment can significantly improve the fatigue life of the workpiece.
Effect of JH vibration aging equipment on welding performance and welding deformation JH vibration aging equipment has improved the weld material, especially the fracture toughness and fatigue limit, indicating that the vibration treatment technology can be used for welding components. The welding method with side vibration is not negligible for controlling cold work, welding deformation, stabilizing the dimensional accuracy of the workpiece, and eliminating the stress of the workpiece. The deformation can be eliminated after welding.
The influence of JH vibration aging equipment on dimensional accuracy JH vibration aging equipment can effectively stabilize the dimensional accuracy of parts. Its function is not only to show that the dimensional accuracy change is small during long-term use, and the size of parts can be achieved in a short time. stable.
