Research on the Applications of Harmonic Frequency Spectrum VSR

Analysis and discuss on the basic principles of harmonic frequency spectrum vibratory stress relief(VSR) technology were taken through comparison experiments on harmonic frequency spectrum VSR and traditional stress relief(TSR),which gave testimony of the effectiveness of harmonic frequency spectrum VSR in preventing distortion of aluminum alloy parts.Besides,harmonic frequency spectrum VSR is proved to be a better way to relieve stress than TSR for small thin-walled structural work pieces and large aluminum alloy structural parts with high strength.Application cases are also given on process technique of harmonic frequency spectrum VSR for large castings of sophisticated parts and large parts of space vehicle.
