摘　　要：石油钻机井架是石油钻机的重要承载部件,其结构杆件多、连接复杂、受力环境恶劣,文章研究了新型前开口"Π"型井架,并对其进行了有限元分析及计算,弹塑性稳定性分析方法所得到的井架稳定安全系数较按弹性稳定性分析方法所算得的结果低。The derrick of oil drilling rig is an importantly bearing component of oil drilling rig. It has many structural members, complicated connections and poor stress environment. This paper studies a new type of front-opening-type "Π" type derrick, and carries out a finite element analysis and calculation to it. The result of stability safety factor of derrick obtained by elastic-plastic stability analysis method is lower than that obtained by elastic stability analysis method.
