doi:10.3901/JME.2017.07.173

Abstract

Abstract:

The cantilever is an important part of jack-up drilling platform. It improves the efficiency and flexibility of drilling operation. The traditional cantilever’s finite element model is built which is selected as the research object, and the bending performance is simulated. Besides, analytical formula is used to analyze the affection laws of the cantilever’s overhung distance on the bending moment distribution; the maximum normal stress is taked as the constraint and the girder’s design height along the overhung distance is derived. Based on this method, the cantilever as variable cross-section is designed. The result shows that the optimized cantilever’s weight can be reduced by 22.903 t, its bending performance improves, achieving the goal of lightweight.

Key words: lightweight, variable cross-section, cantilever
