Experimental Investigation of the Vibro-impact Capsule System

This paper presents an experimental investigation of the vibro-impact capsule system, which has potential applications in capsule endoscopy and engineering pipeline inspection. The experimental results obtained using novel test rig are used to verify the modelling approach where non-smooth multibody dynamics is applied to describe the motion of the system, and comparisons between numerical simulations and experiments are given. After an appropriate re-scaling, the findings of this work could provide a better insight into the behaviour of such systems which are subject to harmonic excitation.
