    • Effects of high frequency drive speed modulation on rotor with continuous stator contact 

      AlZibdeh, Abdullah; AlQaradawi, Mohammed; Balachandran, Balakumar ( Elsevier Ltd , 2017 , Article)
      In many mechanical systems, rotating structures experience continuous rotor-stator contact and torsion motions are dominant in the response. Drill strings used in the oil and gas industry represent one example of rotating ...

    • Influence of Sinusoidal Drive Speed Modulation on Rotor with Continuous Stator Contact 

      Alzibdeh, Abdullah; Al-Qaradawi, Mohamed Y.; Balachandran, Balakumar ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      Torsional vibrations experienced by drill strings can be detrimental to drilling operations. With a goal of understanding torsional vibrations experienced by drill strings and determining means to attenuate undesired ...
