摘要
利用有限元法分析了K型石油钻机井架结构,获得了其结构静力特性和结构屈曲因数,并得到井架固有频率和振型.计算结果表明,JJ162/42-K型石油钻机井架在设计钩载作用下,最大位移出现在井架顶部,最大应力集中在2个前立柱上的第2,第3大节处.
The method of finite element analysis is one most effective kind of numerical value analysis.The finite element analysis for K-type derrick of oil rig is completed with this method.The statistic characteristic and flexuosity coefficient are obtained,and the derrick's frequency and vibration models are also calculated.The result shows that the maximum displacement appears on the top of the derrick's columns,and the maximum stress appears at the second and the third segments of the two front columns.
