Abstract

Drilling rig is a machine that creates holes in the earth subsurface. Mast, a key part of hydraulic drilling rig, is a large steel structure with box section which loads all kinds of workforces. This paper focuses on the design and structural analysis of mast members of hydraulic rig. Stress analysis is conducted on mast structure under different loading conditions. The main aim of this paper is to make mast structure to withstand different load conditions i.e. Lifting drill condition, drilling condition and maximum load condition. The existing mast design is studied and found that stresses and deformations are high. Hence the mast is redesigned using SOLID WORKS and analyzed by FEA. It is found that stress and displacement levels are reduced and the design is made robust. Further, the stress and displacements are also calculated theoretically and compared with results obtained using FEA.
