The article reveals the technological aspects of vibration stabilizing processing of parts, presents the ways of its implementation, considers possible methods of its implementation and its influence on the change of residual stresses of low-rigidity parts. The work suggests ways to improve the efficiency of vibration stabilizing processing, ensuring its use for stabilizing the quality of parts and, as a result, the service life of aircraft. Keywords Vibration-stabilizing treatment, residual stresses, technology, quality of parts.
