摘要
基于对ASME规范与EN1591-1中螺栓法兰接头设计计算方法的比较,分析了确定螺栓载荷中存在的问题。通过有限元分析,计算接头各元件柔度,并建立密封结构的载荷-变形曲线,从而提出了确定合适的螺栓预紧载荷的方法。
By comparing the ASME Boiler and Pressure Vessel Code with the EN 1591 issued by European Commission of Standardization, some problems of existing methods on determining the bolt loads were analyzed. Based on the finite element calculation and analysis, the flexibility of each part and load - deformation curves of the sealing structure were gotten. Finally, an improved method on determining proper value of blot preload was proposed.
