摘　　要：为了对HXJ180海洋修井机在多种复杂工况下的作业强度进行分析,采用命令流的方法建立修井机模型,通过对4种组合工况、8种风向对应的32个子工况下的修井机作业强度进行数值仿真计算,得到修井机位移及等效应力分布云图。根据AISC 360—16规范中的UC值判定法,对各工况下的修井机作业强度进行校核验证。校核结果表明:在所有工况下,最大等效应力点都集中在上移动座立根区域前端,风向对最大应力点位置的影响不大;在2种操作工况下,风向对修井机位移分布的影响较小,最大位移点分别位于井架天车座和气固体管线承重梁区域;而在非预期工况及可预期工况下,风向对井架上体部分及二层台的位移分布有明显影响,最大位移点也主要集中在该区域。所有工况下的构件最大UC值都出现在上移动座立根区域前端处,且最大UC值都小于1,表明该修井机的综合强度足够,满足API标准使用要求。分析方法和相关结果可为钻机、修井机强度校核和设计改进提供借鉴。In order to analyze the operation strength of HXJ180 offshore workover rig under various complex working conditions,the command stream method was used to build a workover rig model.By means of numerical simulation on the operation strength of the workover rig in 32 sub-working conditions corresponding to 4 working conditions and 8 wind directions,the cloud chart of displacement and equivalent stress distribution of the workover rig was obtained.Based on the UC value determination method in AISC 360—16,the operation strength of workover rig under various working conditions was checked and verified.The study results show that under all working conditions,the maximum equivalent stress is concentrated at the front end of the pipe setback region of upper movable base,and the wind direction has little effect on the position of the maximum stress point.Under two working conditions,the wind direction has little effect on the displacement distribution of the workover rig,and the maximum displacement point is located in the region of derrick crown base and bearing beam of gas-solid pipeline respectively.Under the unexpected and expectable working conditions,the wind direction has a significant impact on the displacement distribution of the upper part and monkey board of the derrick,and the maximum displacement point is also mainly concentrated in the region.Under all working conditions,the maximum UC value of the component occurs at the front end of the pipe setback region of upper movable base,and the maximum UC value is less than 1,indicating that the comprehensive strength of the workover rig is enough to meet the operating requirements of the API standard.The analysis method and related results in this paper provide reference for strength check and design improvement of drilling and workover rigs.
