Zukovic, M., Hajradinovic, D., Kovacic, I.: On the dynamics of vibro-impact systems with ideal and non-ideal excitation. The part of the paper where transient solutions are analysed is showing how the system can start as an vibro-impact system and switch to non-impact motion. In reference to different regions the goal is to keep the system from the impact region assuming that the machine should just oscillate. It is pointed out that for which range of the stall torque values the system will have impact solutions or non-impact solutions. Through this analysis impact and non/impact solutions are obtained. The aim of this paper is to show how the system behaves if the installed electromotor is weak or strong one. Based on these results transient motion is also analysed and results are shown in the form of diagrams which are describing the displacement and excitation frequency change in function of time. Results are shown in the form of frequency response diagram, average value of the excitation frequency versus the stall torque value diagram and oscillation amplitude versus the stall torque value diagram for the steady state solutions. The numerical analysis is based on the continuation method of a run up and close down simulation by changing the stall torque value. The equations of motions are derived using Lagrange’s equations. The electromotor characteristic is assumed to be linear and the mathematical model of it is shown in the paper. The system is excited with a DC electromotor via the balanced disk. The disk is attached to an electromotor shaft. The driving slider is connected to a balanced disk with a link. The analysed system consists of an oscillating slider, a hard stop on one side of the oscillator, on the other side the oscillator is connected via a nonlinear spring to a slider. The paper is giving an insight in modelling and numerical analysis of steady state and transient motion of the system. This paper is studying the behaviour of a vibro-impact system with non-ideal excitation where the impacting oscillator is connected to a driving slider with a non-linear cubic spring.
