摘要

基于Abaqus软件对核电站高能管道的甩击过程及Ω形防甩件的防甩性能进行了仿真分析。通过分析常见U型防甩件的变形和破坏过程,提出采用Ω形设计的防甩件取代U型防甩件,并给出了Ω形防甩件的具体几何尺寸。通过有限元软件Abaqus建立管道-Ω形防甩件系统模型,对甩击过程进行数值模拟分析。结果表明,相较于U型防甩件,Ω形防甩件能够显著地降低甩击过程中的应力峰值,减小甩击力,提高高能管道系统的安全性。

Abstract

Based on ABAQUS,the process of the high-energy pipeline rejection and anti-whipping performance of the Ω-shape anti-whipping restraints of the nuclear power plant are simulated and analyzed. By analyzing of the deformation and failure process of common U-shaped anti-whipping restraints,the Ω-shape anti-whipping restraint is proposed to replace U-shaped antiwhipping restraints and the specific geometric dimensions of the Ω-shape anti-whipping restraint are given. The model of pipe-Ω-shape anti-whipping restraints system is established,and its whipping process is analyzed by FEM software ABAQUS,which discloses that the Ω-shape anti-whipping restraint is able to remarkably reduce the stress peak and the maximum whipping force of the pipe--anti-whipping restraints system,thus improve the safety of the high-energy pipe system.
