极限载荷分析作为设备安全分析的新兴技术,是工程强度设计规范中塑性失效分析的重要方法。利用极限载荷分析技术评定核电厂管道横向限制件的极限承载能力。通过算例阐述极限载荷分析技术在核电设备评定中的应用。文中所述的概念和方法,可以推广应用到其他核电设备的弹塑性有限元分析中。 As a new technology of equipment safety analysis, ultimate load analysis is an important method of plastic failure analysis in engineering design codes. Application of Limit Load Analysis Technique to Assess the Ultimate Bearing Capacity of Transverse Limitations of Nuclear Power Plant Pipelines. An example is given to illustrate the application of limit load analysis in the assessment of nuclear power equipment. The concepts and methods described in this paper can be applied to the elasto-plastic finite element analysis of other nuclear power equipment.
