Vibro-impact attachments as shock absorbers [PDF]
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2008 The use of vibro-impact (VI) attachments as shock absorbers is studied. By considering different configurations of primary linear oscillators with VI attachments, the capacity of these attachments to passively absorb and dissipate significant portions of shock energy applied to the primary systems is investigated.

Magnetic Bistability for a Wider Bandwidth in Vibro-Impact Triboelectric Energy Harvesters. [PDF]
Micromachines (Basel), 2023 Mechanical energy from vibrations is widespread in the ambient environment. It may be harvested efficiently using triboelectric generators. Nevertheless, a harvester’s effectiveness is restricted because of the limited bandwidth.

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.

Nonlinear Dynamics of Vibro-Impacting Indenter
Applied Sciences, 2023 We investigated a vibro-impacting indenter interacting with strata in the form of metal or rock samples experimentally and via mathematical modelling. An experimental programme was undertaken on the custom-designed rig at the Centre for Applied Dynamics of the University of Aberdeen.

Stochastic Dynamics of Nonlinear Piezoelectric Vibration Energy Harvesting System with Inelastic Impact. [PDF]
Entropy (Basel)Because the introduction of a vibro-impact structure can widen the bandwidth and improve the harvesting efficiency of the vibration energy harvesting (VEH) systems, an analytical method for a VEH system based on vibro-impact is proposed to employ the ...

Vibro-Impact Response of a Cracked Bar [PDF]
Shock and Vibration, 2011 The presence of a crack in a structure affects its dynamic behaviour under working conditions. Cracks introduce nonlinearities into the system; the use of such nonlinearities for damage detection should be investigated. A model of a one-dimensional cracked cantilever bar subjected to longitudinal harmonic excitation is used to analyse a vibro-impact ...
