Unilateral vibro-impact systems — Experimental observations against theoretical predictions based on the coefficient of restitution

Published in Journal of Sound and Vibration, 2018

Highlights

• Reproduce empirical observations to a certain level, validating analytical predictions.
• Discussion of common techniques for analysis of unilateral vibro-impact problems.
• Presentation of experimental data for 3 gap configurations: loose, neutral and tight.
• Dependence of the coefficient of restitution to forcing frequency and pre-contact velocity is shown empirically.
• Discussion on model tuning for unilateral vibro-impact experiments.
