Scope of Application:
The vibration stress relief system is mainly used in aerospace, automotive manufacturing, shipbuilding, and mechanical manufacturing industries. These fields place extremely high demands on the precision and stability of components. As an effective stress-relief method, vibration stress relief can significantly improve dimensional stability and service life of components.By utilizing the principle of resonance, the vibration stress relief system reduces and homogenizes residual stresses generated inside workpieces during welding, casting, machining, and mechanical manufacturing processes. As a result, it effectively enhances the strength of the processed parts, reduces deformation and cracking, and ensures more stable dimensional accuracy.
Product Overview:
Vibration stress relief is a process that uses the principle of resonance to eliminate and homogenize residual stresses in metal castings, forgings, welded structures, non-ferrous metals, and other components, thereby preventing dimensional deformation and cracking.As a modern method for residual stress elimination, vibration stress relief is based on harmonic resonance theory. Appropriate excitation equipment is rigidly fixed at suitable positions on the workpiece. By adjusting the excitation force and frequency, the workpiece is forced to vibrate within its resonant frequency range under periodic external forces. After a certain period of vibration, residual stresses are reduced and evenly redistributed, achieving improved dimensional stability of the component.
Equipment Advantages:
The application of the vibration stress relief system not only improves the mechanical properties of components, such as strength and fatigue life, but also reduces stress corrosion and prevents or minimizes the formation of microcracks caused by processes such as heat treatment and welding.In addition, due to its simple structure and easy portability, the vibration stress relief system can be used for on-site treatment in virtually any location, without limitations on component size or material. Components ranging from tens of kilograms to several hundred tons can be treated using vibration stress relief technology. In particular, for large components where thermal stress relief is impractical or impossible, vibration stress relief offers significant advantages.
