Modeling of vibrational impact motion of mobile-based body

The paper deals with vibrational impact motion of a mobile-based body on an inclined plane, which is a characteristic for vibrational alignment of components subjected to an automated assembly. The alignment model is presented by a two-degree-of-freedom vibro-impact system in which the moving body is impacting the plane obliquely. Properties of the vibrational impact motion under kinematical excitement of the moving body and under the excitement of the plane in two perpendicular directions were investigated by numerical methods. It was determined that impact displacement occurs under transient regimes of motion from static to dynamic state of equilibrium. Dependencies of maximum displacement of the body and average displacement velocity on force of elastic resistance, amplitude of plane vibration in the direction of the displacement, and phase angle between the perpendicular members of vibration components were established. Zones of system and excitement parameter combination when the vibrational impact motion occurs were defined.
