Published Online: May 13, 2019
...Jialin Tian; Genyin Li; Liming Dai; Lin Yang; Hongzhi He; Shuhui Hu Torsional stick–slip vibrations easily occur when the drill bit encounters a hard or a hard-soft staggered formation during drilling process. Moreover, serious stick–slip vibrations of the drill string is the main factor leading...

Influence of Torsional Motion on the Axial Vibrations of a Drilling Tool

Sergey A. Voronov, Alexander M. Gouskov, Alexey S. Kvashnin, Eric A. Butcher, S. C. Sinha
Journal: Journal of Computational and Nonlinear Dynamics
Publisher: ASME
Article Type: Research Papers
J. Comput. Nonlinear Dynam. January 2007, 2(1): 58–64.

Analysis of the Chatter Instability in a Nonlinear Model for Drilling

Sue Ann Campbell, Emily Stone
Journal: Journal of Computational and Nonlinear Dynamics
Publisher: ASME
Article Type: Research Papers
J. Comput. Nonlinear Dynam. October 2006, 1(4): 294–306.

Published Online: April 20, 2006
...Sue Ann Campbell; Emily Stone In this paper we present stability analysis of a non-linear model for chatter vibration in a drilling operation. The results build our previous work [ Stone, E., and Askari, A., 2002, “Nonlinear Models of Chatter in Drilling Processes,” Dyn. Syst., 17(1), pp. 65–85...
