Definition of VSR(vibratory stress relief)
It describes a physical process is this: that is tightly controlled using a vibration energy,
the metal work piece is processed to resolve the workpiece during and after the processing of
the internal and residual stresses occur dimensional changes resulting load capacity and resistance to change.VSR（vibratory stress relief) to eliminate, reduce or homogenizing the residual stress of the metal workpiece, the workpiece to improve resistance to static and dynamic load, the deformation resistance, stability, efficacy superior dimensional accuracy.

VSR(vibratory stress relief) principle
From the micro level analysis, VSR can be regarded as a kind of cyclic loading is applied in the form of an additional stress on parts. When the workpiece is subjected to vibration applied to the alternating stress on parts and components in the residual stress superposition. When the result of superposition of the stressreaches a certain value, the worst part of the stress concentration will exceed the yield limit of the materialis plastically deformed. This is where the residual plastic deformation reduces the stress peaks and strengthen the metal matrix, and then the vibration but also in other parts of the stress concentration is generated on themore serious the same effect until the vibration superposition of additional stress and residual stress of thealgebraic and not cause any part of the plastic deformation, at which time, and both vibration to eliminate residual stress and strengthening of metal on the end of the process.

3000 series full-automatic vibratory stress relief equipment

          The real color LCD screen display the curves and data dynamically,the vibrating process and the curve trend are clear at a glance.

          Judge the process parameters suitable or not itself automatically and provide the amendments to the program,to realize the man-machine dialogue prompt function.

          Full-automatic operation,to prevent the personal factor(with both manual and semi-automatic).

          Adopting the technology of double-loop design and strong anti-jamming capability of plus-width modulation technology.

          Dynamic tracking function can ensure vibration treatment is always in the standard of sub-resonance region.

          The motor only started once during the whole vibration aging process,it can save 1/2 auxiliary testing time.

          Selecting the excitation freqency to aging as per the optimized process according to the advanced spectrum analysis technology.

          Printing the overlapping curves of a-n and a-t and data comparison automatically,In order to test them and make permanent presarvation.

          This series is suitable for the major components demanded vibrating aging of eliminating stress strictly.

          Achieving three-dimensional vibration and measuremeat on the workpiece,improve the level of stress relief.
