| 摘 要： | 核级管道的应力分析是为了保证管道自身和与其相连的设备、支架的安全.分析内容包括3个方面:计算管道应力,并使之满足RCC-M规范规定的限值要求;计算管道对与其相连的机器、设备的作用力,并使之满足标准规范的要求,保证机器、设备的安全;计算管道对支吊架的作用力,为支吊架的设计提供依据.管道应力分析工作的步骤是:首先,对管道所在系统的功能和工况参数、管线的布置情况进行详细的了解,划分分析范围;其次,根据管道ISO图用软件建立分析管线部分的几何模型,并定义材料属性;然后,按照规范规定的载荷组合形式加载;最后,计算、评定并输出支反力,核级管道的应力分析不仅可保证管道、支架、设备的安全,而且可优化设计,在核电厂建造和运行中起到重要作用.
