Stress Analysis of mast structure for water-well drilling machine

Mechanical Engineering

This research paper contains stress analysis of the mast structure for water well rotary drilling rig. As an important support and loading structure for main actuating mechanism of a rotary drill, the mast is important component in drilling operation. It plays important role for drilling to ensure normal operation and work quality. According to the extreme condition, load is applied to the mast structure, stress analysis conducted on three different types of mast structure in Ansys software. The Ansys results are verified experimentally. This study presents a finite element model of the entire tower structure of water well drilling rig. 3D graphics software Catia is firstly used to establish solid model of the tower structure of water well drilling rig and then the model is imported into the finite element analysis software Ansys to calculate the working characteristics and to perform the deformation analysis of the tower structure of rotary drilling rig in the Ansys Work bench. The critical buckling stress is calculated by the conventional formula.
