Modeling of Vibrational-Centrifugal Strengthening for Functional Surfaces of Machine Parts

Microrelief quality indicators and operational characteristics of machine parts are implemented by using rational finishing treatment (conventional cutting methods) and finishing strengthening (chemical and thermal treatment and methods of surface plastic deformation) during their manufacturing. The main difference between vibration technologies and traditional finishing methods of machining and static deformation of SPD is the possibility of forming regular microreliefs, which allows for achieving the geometric parameters of the quality of the surface layer for machine parts. In this paper, dynamic processes are modeled using electromagnetic vibration-centrifugal strengthening devices. The Poincare and Lyapunov method of small parameters was used to develop a system of differential equations to study the laws of motion of the main elements of a vibration-centrifugal strengthening device with an electromagnetic drive. The dynamics of the variation of the amplitude spectrum in time and the phase portraits of the executive elements for the non-working and working modes of operation of the vibration-centrifugal amplification device were analyzed. Further research on electromagnetic vibration-centrifugal strengthening devices is suggested.
