This paper presents experimental and numerical investigations of the complex drill-string vibration, with particular attention to the helical buckling of drill-strings and its influence on the system dynamics. The analysis is conducted using a novel experimental drilling rig, capable of exhibiting of all major types of drill-string vibration, including torsional, axial and lateral modes, which utilizes real industrial drill-bits and rock samples. A good qualitative and quantitative agreement between the experiments and numerical model is demonstrated.
