基于ASME标准的高温压力容器高温疲劳强度设计方法比较
ASME Code Based Comparison of High Temperature Fatigue Strength Design of High Temperature Pressure Vessel
摘要
Abstract
Many failure modes are encountered during the whole service life of pressure vessels at elevated temperature,including creep,creep-fatigue and so on.Therefore,the structural design of high temperature pressure vessel is the bottleneck and difficulty that restrict the realization of high technology process.Focusing on the creep and creep-fatigue failure modes,gives an introduction to the differences of ASME codes NB and NH on stress criteria,strain and deformation criteria,and creep-fatigue strength criteria.Meanwhile,an example of a catalyst for hydrogenation reactor is presented,using the elastic finite element method to discuss the main differences of fatigue strength between ASME codes NB and NH.关键词
