摘要
本研究探讨了石油化工大型静设备安装中的变形与应力控制方法。以一台高压塔器为例,建立有限元模型,分析最大变形位移、节点应力与刚度分布,结合现场监测数据验证仿真精度。得到结果,主吊阶段最大变形为14.3mm,应力峰值为192.7MPa,现场监测最大位移为14.1mm,仿真吻合度高。研究结果表明,优化吊装路径与焊接工艺,结合数字化监测反馈,可显著提升安装质量与结构安全性。
This study investigates deformation and stress control methods during the installation of large static equipment in the petrochemical industry.Taking a high-pressure tower as an example,a finite element model was established to analyze the maximum deformation displacement,nodal stress,and stiffness distribution.The simulation accuracy was validated against field monitoring data.The results indicated that the maximum deformation during the main hoisting stage was 14.3 mm,with a peak stress of 192.7 MPa.The field-monitored maximum displacement was 14.1 mm,demonstrating a high degree of agreement with the simulation.The research findings suggest that optimizing the hoisting path and welding procedures,combined with digital monitoring and feedback,can significantly improve installation quality and structural safety.
