Nonlinear Model and Qualitative Analysis for Coupled Axial/Torsional Vibrations of Drill String

A nonlinear dynamics model and qualitative analysis are presented to study the key effective factors for coupled axial/torsional vibrations of a drill string, which is described as a simplified, equivalent, flexible shell under axial rotation. Here, after dimensionless processing, the mathematical m...
