EXTENDED SERVICE LIFE – DIMENSIONAL STABILITY – ON-SITE TREATMENT
Mechanical Stress Relief
The stages of the Vibratory Stress Relief (VSR) process
Isolate from the ground
The workpiece is isolated from the ground and placed on rubber pads.
Vibration Unit – Vibration Sensor
The vibration unit and vibration sensor are attached to the workpiece.
Resonance Analysis
A resonance analysis is performed to determine the resonance frequency of the workpiece.
Mechanical Vibrations
Mechanical vibration is applied for a specific duration at the resonance / subharmonic frequency
Evaluate the effectiveness
At the end of the process, the resonance analysis is repeated, and the results are compared with the initial state to evaluate the effectiveness of the treatment.
Resonance Frequency
For an effective Vibratory Stress Relief (VSR) application, the resonance frequency of the workpiece must be precisely identified. To achieve this, we utilize 16-bit resolution signal processing technology, which allows us to reach a high level of accuracy.
To Evaluate the Effectiveness
The material damping ( hysteretic damping ) reduces when the residual stress relieved. The peak of acceleration
becomes higher and/or the resonant frequency becomes lower if the VSR treatment is effective.
Ease of Application
Stress Relief can be performed on-site at any stage of production using the mobile device Mevit VSR 30.
