摘要

以某化工园区的架空管道方形补偿器为研究对象,该补偿器管廊有10组立柱、4层管架及27根管道,输送不同温度和压力工况的流动介质。在考虑重力、介质温度、流动对管道作用力等因素的基础上,系统、完整地建立ANSYS有限元模型,并进行了热流固耦合计算,得到了架空管道方形补偿器的位移、轴力、剪力、弯矩及应力等参数分布,找出这些参数的最大值及其位置,对二次应力进行校核验算,判断了方形补偿器的可靠性。旨在探索一套针对复杂架空管道实际应用的安全风险评估方法,为架空管道的运行安全提供技术支持。
        In this study,the square-shaped compensator for the overhead pipeline in a chemical industrial park was selected as the research object. The pipeline gallery had 10 sets of support columns,4-layer pipe racks and 27 pipes to transport the flow medium in different temperature and pressure. By taking into account the factors such as gravity,medium temperature,flow force on the pipeline,etc,the ANSYS finite element model was established sophisticatedly to perform the thermal fluid-solid coupling calculation. The distributions of displacement,axial force,shear force,bending moment and stress of the square-shaped compensator were obtained. The maximum values and the corresponding positions in these distributions were found and analyzed. The reliability of the squareshaped compensator was judged by checking the secondary stresses. The study aims to explore a safety assessment method for the application of complex overhead pipelines,and to provide solid technical support for the safety operation of overhead pipelines.
