Drill string nonlinear vibrations: Experimental studies and finite-element analysis
Kanzari M.; Shahin I.M.; Alqaradawi M.Y.; Balachandran B. ( Institute of Physics Publishing , 2018 , Conference Paper)In the present work, nonlinear vibrations of drill strings are studied. A laboratory scale arrangement consisting of a flexible rod with rotor-stator system is used to study the system dynamics. A finite-element model has ... -
Nonlinear stochastic drillstrings vibrations: Parametric study for stick-slip suppression
Alqaradawi M.Y.; Kanzari M.; Balachandran B. ( Institute of Physics Publishing , 2018 , Conference Paper)Unstable vibrations caused by the transition between static and kinetic frictions produces stick-slip motions which is one of the primary causes of poor drilling efficiency and mechanism failure in the drilling process. ...
