Experimental verification of the vibro-impact capsule model.
Liu, Yang; Pavlovskaia, Ekaterina; Wiercigroch, Marian
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 experimentally 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 into the vibro-impact systems subject to nonlinear friction, and the experimental rig can be used to predict the dynamic behaviour of these systems.
