| Abstract: | Based on allowable stress peak value method,the engineering budget method of the oil-drilling rig substructure steel structure's fatigue life was researched,computational method of the fatigue load spectrum and equivalent stress amplitude coefficient were analysed when the rig is tripping,the structure path how to compute the rig structure's fatigue life was proposed.At last the 70LDB marine drilling rig was taken for an example which fatigue life was computed.The result indicated that this rig's design is ... |
