Journal ArticleDOI
Synchronization of clocks
Marcin Kapitaniak,Marcin Kapitaniak,Krzysztof Czolczynski,Przemyslaw Perlikowski,Andrzej Stefanski,Tomasz Kapitaniak +5 more
TL;DR: In this paper, the authors consider the synchronization of two clocks which are accurate (show the same time) but have pendula with different masses and give evidence that almost antiphase synchronization was observed by Huygens in XVII century.
Journal ArticleDOI
Unveiling complexity of drill–string vibrations: Experiments and modelling
Marcin Kapitaniak,Vahid Vaziri Hamaneh,Joseph Páez Chávez,Joseph Páez Chávez,Krishnan Nandakumar,Marian Wiercigroch +5 more
TL;DR: In this article, the authors investigate complex drill string dynamics on a novel experimental rig, capable of reproducing all major types of drill string vibrations, such as stick-slip oscillations, whirling, drill-bit bounce and helical buckling of the drill string.
Journal ArticleDOI
Synchronous states of slowly rotating pendula
Marcin Kapitaniak,Marcin Kapitaniak,Krzysztof Czolczynski,Przemyslaw Perlikowski,Andrzej Stefanski,Tomasz Kapitaniak +5 more
TL;DR: In this article, a review of the studies on the synchronization of rotating pendula and compare them with the results obtained for oscillating pendula is presented. And the authors give evidence that synchronous states are robust as they exist in a wide range of system parameters and can be observed in a simple experiment.
Journal ArticleDOI
Experimental studies of forward and backward whirls of drill-string
TL;DR: In this paper, the authors investigate forward and backward whirls of a drillstring using a novel experimental drilling rig (Wiercigroch, 2010) capable of reproducing major types of drill-string vibration, including stick-slip, bit-bounce and whirling.
Journal ArticleDOI
Suppression of drill-string stick–slip vibration by sliding mode control : Numerical and experimental studies
TL;DR: Wiercigroch et al. as mentioned in this paper investigated experimentally and numerically suppression of drill-string torsional vibration while drilling by using a sliding mode control and found that a significant reduction in vibration amplitude has been observed when using the sliding controller.
