【摘要】 本文叙述了核电站蒸汽发生器一次侧整体(包括下封头、进出水接管、人孔、水室隔板、 管板、部分二次侧筒体)及管板,在内压和接管载荷作用下的三维有限元应力分析。得出一次侧各部件相互间的影响,管板的孔桥应力和孔边峰值应力。计算结果与轴对称有限元应力分析作了比较。对关键部位按ASME规范第Ⅲ篇的应力强度极限作了评价。更多还原

【Abstract】 This report presents the results of a tridimensional finite element stress analysis of primary side and tube-sheet of a PWR steam generator. It is subjected to internal pressure load and external load at the safe-end of the nozzle. The interacted effect of different components,maximum peak stress and minimum ligament stress of tube-sheet were obtained. The results of this tridimensional calculation are compared with results of axisymmetrical finite element analysis.At major locations the results have been evaluated in compliance with stress limits of AMSE code section III.更多还原
