Stress Analysis and Evaluation of Heavy Double-Hole Pipe Clip

China Fast Reactor Research Center, China Institute of Atomic Energy, Beijing, 102413, China

摘要: 简要介绍了核电厂厂房中大量使用的重型双孔管夹的材料、结构等参数,并运用有限元分析软件ANSYS建立了重型双孔管夹的有限元模型,计算了重型双孔管夹的分类应力强度、管夹螺栓应力、管夹螺栓连接件应力。与法国的《压水堆核电厂机械设备设计和建造规则》(RCC-M)相关应力评定限制的对比表明,在所承受载荷作用下,重型双孔管夹满足规范对其强度的要求。

Abstract: The material and structure of the heavy double-hole pipe clip used widely in the nuclear power plants are briefly introduced,and the finite elment model of the heavy double-hole pipe clip is built using ANSYS,to calculate the classified stress strength of double-hole pipe clip,the stress of bolt for pipe clip and the stress of the bolt joint.Using the computed results,the stress of the pipe clip is strictly evaluated according to the RCC-M codes and standards.The results show that the stress of pipe clip under all loads satisfies the code.
