Abstract
Abstract In this paper an experimental verification of the vibro-impact capsule model proposed by Liu et al. in [1–3] is presented. The capsule dynamics is investigated xperimentally by varying the stiffness of the support spring, and the frequency and the amplitude of excitation. The novel design of the experimental set up is discussed, and comparisons between the experiments and numerical simulations are presented showing a good agreement. The conducted bifurcation analysis indicates that the behaviour of the system is mainly periodic and that a fine tuning of the control parameters can significantly improve the performance of the system. The main findings provide a better insight for
the vibro-impact systems subject to nonlinear friction, and the experimental rig can be used to predict the dynamic behaviour of these systems.
