Journal of Advanced Mechanical Design, Vol. 7, No. 2, 2013 Systems, and Manufacturing The Evaluation of Braking Performances of Mechanical Brake System on Oil Rig* Yu WANG** and Li LIN*** **Key laboratory on Deep Geo-Drilling Technology of the Ministry of Land and Resources, China University of Geosciences, Beijing, China E-mail: wangyu203@ ***Institute of Mechanical and Electrical Engineering; China University of Petroleum, Beijing, China Abstract This paper proposes a novel method for evaluating the braking system on oil rig. The Evaluation indexes, braking capacity, response speed control accuracy and braking efficiency, are put forward according to the drilling safety, benefit, quality and so on. The experimental apparatus to the performances of brakes was built by measuring the relation between the braking pressure, torque and rotation speed. The performances of pneumatic disc brake, hydraulic disc brake and pneumatic band brake are researched b
