Improvement Design of Vertically-telescopical Substructure of ZJ30 Rig based on the theory of finite element
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 4
Abstract
According to the actual structure and stress state of the ZJ30 rig derrick and substructure, the beam element model of the derrick and the entity model of the substructure for finite element analysis were established in the article. Considering three most dangerous working conditions, the derrick rising, maximum hook load and casing installation, the load on the substructure was calculated by the software ANSYS ,a finite element analysis software the force and deformation on the part of the substructure were analyzed. The weak parts with the big stress and deformation were redesigned and recalculated based on the above to ensure the safety of the substructure in operation. Keywords: the substructure of rig, structure, finite element
