核级转子流量计测量管段应力分析与评定

Stress Analysis and Assessment for Measurable Part of Variable Area Flowmeter

为论证流量计在各种工况下是否保持结构的完整性,利用有限元分析软件ANSYS对流量计测量管段进行分析和改进。利用计算结果,严格按照RCC-M规范对转子流量计测量管段作了应力评定。应力分析评定结果表明,转子流量计测量管段满足RCC-M对安全3级设备结构完整性的要求。

Under different conditions whether the structural integrity of the variable area flowmeter can be ensured was demonstrated.In the paper,using the finite element ana-lysis software ANSYS,the model on measurable part of the variable area flowmeter was built and modified.Utilizing the calculation results,the stress assessment of the variable area flowmeter was carried out strictly according to the RCC-M codes.And it shows that measurable part of variable area flowmeter is satisfied with the requirement of RCC-M.
