Modelling of a vibro-impact capsule system [PDF]
International Journal of Mechanical Sciences, 2013 The model of a vibro-impact capsule system is studied in this paper to provide a fundamental understanding of its dynamics for potential medical and engineering applications. The system consists of a capsule having a main body which interacts with an internal mass driven by a harmonic excitation.

A comparative study on the two vibration driven locomotion systems in various friction levels
Vietnam Journal of Mechanics, 2021 This paper presented comparison results of two locomotion models: a pure-vibration driven and a vibro-impact driven system. In experiments, the friction force can be varied without changing the internal and the body masses.
