This paper demonstrates a theoretical and experimental study on a universal vibro-impact
system with bidirectional drift. With a dedicated experimental rig that is able to verify …

Vibro-impact drilling has shown huge potential of delivering better rate of penetration,
improved tools lifespan and better borehole stability. However, being resonantly instigated …

Impacting systems are widely used in many engineering applications, such as self-propelled
robots, energy harvesting and percussive drilling, which exhibit rich and complex nonlinear …

For the real-time characterisation of an inhomogeneous impact inhibiting constraint such as
downhole rock layers, an unconventional method using machine learning (ML) and drill-bit …

Aluminium matrix composites (AMCs) are challenging to machine due to its abrasive
characteristics. Because of the broad adoption of MMCs, it is vital to create sufficient …

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 …

Modern drilling machines designed for the destruction of rocks have a diverse structure,
various performance characteristics and in most cases a well-defined limited scope of …

An increase in the efficiency of work related to the destruction of rock by impacts, with a
constant impact energy determined by the kinetic energy of the anvil-block, is achieved by …

One of the main vectors for the development of a mining enterprise should be the formation
and consistent implementation of key tasks in the field of occupational health and safety. The …

The use of wireless sensors for patient monitoring and extensive use of telemedicine has
thrown a challenge for medical professionals as they have to rely on sensor signals for …
