Experience of application of the strong concentrated ultrasonics for activation of assembly processes of screw connections with tension and a thread-forming is considered. The analysis of possible mechanisms of action of ultrasonic oscillations (USO) on the dislocation nature of plastic deformation is provided. Constructions of technology equipment with the wave concentrators for summing of USO with dfferent frequencies and amplitudes are provided. Results of the pilot researches of action of the concentrated USO on thread-forming torques are given and also we analyzed the inflence of a high-frequency component of USO and processing speed on force factors of process. The experimental dependences for calculations of torques in the mode of action of the concentrated USO are set. Lowering of the moments from action of a basic, i. e. low frequency component of USO and also high-frequency component is experimentally established. It is proved that application of the concentrated USO considerably reduces force strength of a thread-forming process and increases reliability of operations.
