INVESTIGATION OF THE STEADY STATE OPERATION CONDITIONS OF ROTATIONAL VIBROACTUATORS

Abstract

The paper presents theoretical investigation results of steady state motion regimes of rotational wave vibroactuator performed on the basis of simplified model of nonlinear vibrating system. The point contact type input - output link interaction of the vibroactuator is analyzed in case of kinematic excitation i.e. under the assumption of optimal vibration parameters of the contact point (elliptical motion with the defined amplitude ratios along two perpendicular axes and the corresponding phase shift ensured by geometrical parameters, excitation zones pattern and multiphase excitation scheme) with the focus made on the investigation of surface characteristics of the rotor. Four types of motion of rotational vibroactuator are analyzed: two contact types with no slipping and two contact types with the phenomena of slipping. The system of equations for the determination of the parameters of steady state type of motion is obtained.
