FORCED VIBRATION ANALYSIS OF A MULTIDEGREE IMPACT VIBRATOR

Journal of Sound and Vibration, 1998
The dynamics of a multidegree impact vibrator subject to harmonic loading is investigated. The system is represented by a lumped mass model which hits and rebounds from a rigid wall during vibration. The periodic solution to the equations of motion with $N$ forcing cycles and $P$ impacts is formulated.
