The operation of oil well drilling is essential for the production of oil and gas it is the key process in huge oil and gas production and exploration industry that oil well drilling takes place in a wide range of geographical and climate environment operating in both offshore and onshore. Phenomena that may cause deprived operational performance and even develop into the catastrophic failure of the well is the presence of vibrations in the drill string; axial, torsional and transverse vibrations. In this paper, an experimental device for in investigating drilling string dynamics in a vertical well was designed and set up together with the sudden hard brake at very high speed. Drill string set up is examined in different speed with brake and without the brake. Data acquisition recorded by using sensors; encoder and accelerometer in LabVIEW NI-environments. With and without brake motor driving voltage responds linearly to the rotational speed, and single sided magnitude spectrum measured for different speed.
