摘要:
为了确保室外架空燃气管道的安全性,基于ABAQUS软件,建立了6.5 m安装间距条件下,2 mm厚度、4 mm厚度、2 mm厚度加20 mm斜筋、4 mm厚度加20 mm斜筋4种支架模型以及3 m安装间距条件下,4 mm厚度加20 mm斜筋支架模型,并分析了不同条件下各支架的变形及应力分布情况。结果显示,管道支架间距6.5 m时,2 mm厚度最大位移为4.14 mm,应力峰值为235 MPa;4 mm厚度时最大位移为2.09 mm,应力峰值为225 MPa;2 mm厚度加20 mm斜筋时最大位移为3.90 mm,应力峰值为237 MPa;4 mm厚度加20 mm斜筋时最大位移为1.46 mm,应力峰值为215 MPa。管道支架间距3 m时,4 mm厚加20 mm斜筋的支架的峰值位移降低至0.66 mm,应力峰值降低至191 MPa。研究表明,增加支架壁厚、加斜筋、缩小管道支架间距等均可降低支架的变形和应力,满足燃气管道安装工程的要求。
Abstract:
In order to insure the security of outdoor overhead gas pipeline, based on ABAQUS software, bracket models including in the condition of 6.5 m installing space 2 mm thickness, 4 mm thickness, 2 mm thickness with 20 mm diagonal reinforcement,4 mm thickness with 20 mm diagonal reinforcement, and in the condition of 3 m installing space 4 mm thickness with 20 mm diagonal reinforcement were established to analyze bracket deformation and stress distribution. According to the analyzed results,in the condition of 6.5 m installing space,the maximum displacement of 2 mm thickness was 4.14 mm,and the peak stress was 235 MPa;the maximum displacement of 4 mm thickness was 2.09 mm,and the peak stress was 225 MPa;the maximum displacement of 2 mm thickness with 20 mm diagonal reinforcement was 3.90 mm,and the peak stress was 237 MPa;the maximum displacement of 4 mm thickness with 20 mm diagonal reinforcement was 1.46 mm,and the peak stress was 215 MPa. Under the condition of 3 m installing space,the maximum displacement of 4 mm thickness with 20 mm diagonal reinforcement was 0.66 mm,and the peak stress was 191 MPa. The research showed that increasing wall thickness of bracket,adding diagonal reinforcement,reducing installing space of bracket could reduce bracket deformation and stress distribution and meet the requirements of natural gas pipe installation project.
