The VSR future and its effect-jingta

Vibration Stress Relief future and it is the effect of VSR can be regarded as an additional stress in the form of a cyclic load applied to the parts. Known engineering materials used is not an ideal elastic body, the interior of the existence of different types of micro-defects, the cast iron is the existence of a large number of shapes of cutting the metal body of the graphite.Therefore whether it is steel, cast iron or other metal, microscopic defects in the vicinity there are varying degrees of stress concentration. When subjected to vibration, the alternating stress applied to the parts on the parts of the residual stress is superimposed. When stress superposition results reach a certain value, the most serious part of the stress concentration will exceed the yield limit of the material is plastically deformed. This plastic deformation reduced there residual stress peak and reinforced metal matrix. 

Then, vibration in others stress concentrated to produce the same effect on the more serious part, until the vibration of additional stress and residual stress superimposed algebra and can not cause any plastic deformation of the parts of the date at this time, will no longer generated to eliminate vibration and homogenized role of residual stress and strengthen the metal. Less investment in the production cycle is short and easy to use, emissions and radiation pollution save energyVibration Stress Relief reduce the cost of research and practical application proved that the the VSR workpiece aging effect in coal, heavy oil or gas heat aging furnace, basic and electric furnace similar aging effects, not only because the VSR overcome the uneven heat aging furnace caused to eliminate stress non-uniformity of the problem, and to avoid the the workpiece heating and reduce the impact of its resistance to deformation, so the general processing of the workpiece by the VSR than the average The dimensional stability of the thermal aging treatment of the workpiece can be increased above 30%. VSR equipment technology is not the venue, with the people improve environmental requirements, thermal aging furnaces flue gas, dust, slag problems have restricted VSR can completely avoid VSR technology countries have been to promote the cause Blind hole for Residual Welding Stress Elimination http://steelpergolas.blogspot.com/2012/12/blind-hole-for-residual-welding-stress.html
