Abstract

The rod model of the resonant vibro-impact module with an electromagnetic drive is considered. Construction’s design implemented an asymmetrical elastic characteristic by one flat spring with two absolutely rigid intermediate supports. Eigenfrequency is defined for corresponding location intermediate supports based on the finite element method. Stress-strain state of the elastic element is graphically represented at the expense of static displacement of local mass. Contact task is considered and contact force between the flat spring and cylindrical support is calculated. Also, contact stiffness is determinate. The parameters of volumetric stress state of the contact, calculated analytically and by modeling in SolidWorks Simulation are shown. The dynamics of the vibro-impact rod system with kinematic’s disturbance is modeled. Contact and equivalent stresses during operation of the vibro-impact rod system are determined.
