Principle of Vibration Aging Equipment Process:
Vibration aging originated from knocking aging and involves using aging equipment to induce resonance in the workpiece being treated. This resonance transfers a certain amount of vibration energy to all parts of the workpiece, causing microscopic plastic deformation internally. The distorted crystal lattices gradually restore balance, thereby eliminating and equalizing the residual stress within the workpiece, ultimately preventing deformation and cracking during processing and use, ensuring the stability of the workpiece's dimensional accuracy.
Vibration Ageing complete machine components and their characteristics
Vibration aging equipment is composed of a controller, exciter, sensor, elastic pad, printing system, auxiliary tooling, and related connection wires. It is easy to operate and convenient to use. With the increasing awareness of energy conservation and emission reduction and the practical effects of vibration aging technology itself, vibration aging equipment is increasingly being applied in the production process and is currently a practical device for eliminating residual internal stress in China. Practice has proven that replacing heat aging with vibration aging can save over 90% of energy, improve deformation resistance by over 30%, enhance size stability by over 30%, and extend fatigue life by over 20%. The aging time generally requires only 15-40 minutes and is not limited by the weight or size of the workpiece. It can be scheduled between processes. It has the advantages of low investment, low operation costs, and simple operation, and is increasingly applied in the production and processing process.

Vibration Aging Mechanism
The essence of vibration aging involves applying a dynamic stress to the workpiece through vibration. When this dynamic stress is叠加 with the workpiece's residual stress, it reaches or exceeds the material's micro-yielding limit, causing either micro or macro local or overall elastic-plastic deformation in the workpiece. Concurrently, it reduces and equalizes the residual stress within the workpiece, ultimately preventing deformation and cracking, and stabilizing the workpiece's dimensions and geometrical accuracy.
