The Stress Analysis of Drilling Derrick Structure Based on Finite Element Method

Article Preview

Abstract:

Oil-drilling derrick is the most important integrant of the equipments in oil industry and is also a giant load bearing structure. In this paper, the 3D geometric model of the derrick is created by commercial finite element analysis (FEA) software ANSYS, and the static stresses under several working conditions are analyzed. The displacement and stress distribution of the derrick acquired can lay the theoretical basis for the optimization design of structural and material choices of the derrick further.
