Stick-Slip Analysis of a Drill String Subjected to Deterministic Excitation and Stochastic Excitation
Using a finite element model, this paper investigates the torsional vibration of a drill string under combined deterministic excitation and random excitation. The random excitation is caused by the random friction coefficients between the drill bit and the bottom of the hole and assumed as white noi...
