摘　　要：折臂抓管机是深海钻机管处理系统的关键设备,文中利用Ansys软件建立了折臂抓管机机械臂的有限元模型,通过计算得到模型的应力大小和分布,根据应力线性化原理提取了关键部位的应力状态,进行分类识别、提取和评定,给出了应力强度评定结果,为此类非标准件的应力计算和结构优化提供了参考。The folding-arm grasping pipe machine is the key equipment of the deep-sea drilling ng pipe handling sys- tem. The paper introduces the finite element model developed for the mechanical arm of folding-arm grasping pipe machine in Ansys to get the model stress and distribution through calculation and stress state of critical parts based on the stress line- ar theory, obtain the strength assessment result through classification, collection, and evaluation, and provide reference for stress calculation and structural optimization of these non-standard parts.
