Vibratory Stress Relief

Some production parts have residual stresses caused by the production process after production. If these stresses are not released, after installation and operation of the desired part, especially in environments with vibration or high temperature, these stresses are released and cause the shape of the part to change and change the balance of the rotor. Large production rotors by welding usually face this problem.
To avoid this problem, it is necessary to de-stress the part before balancing and assembling. There are different methods for vibrational stress relief. Thermal stress relief is the most common methods of vibration stress relief. But in many cases, this method changes the shape of the rotor and makes it defective, after all, it is very difficult and expensive to prepare a suitable furnace with the ability to control the uniform temperature for large parts. Therefore, the vibration tensioning method is used today with much lower costs and higher operating speed.
Tavator Sepahan Engineering Company has implemented various vibration stressing projects with related facilities.

Procedure

For this purpose, the part in question is properly suspended and vibration with a specific amplitude is applied to the part at one point to affect all possible stressed points. By monitoring the changes in the natural frequency of the part, the termination time of tensioning is determined.
