【摘要】 加氢反应器在服役过程中会受到高温和循环载荷的共同作用,设计时必须同时考虑蠕变和疲劳的影响。ASME规范案例2605提供了一种用于加氢设备的蠕变疲劳寿命设计方法。本文借助有限元分析软件ABAQUS,以加氢设备的接管部位为例,基于新版案例2605中的方法,对新型加氢反应设备进行蠕变疲劳寿命校核。同时,分析了疲劳设计曲线的生成方法、超标准循环次数的设计、设计参数对蠕变疲劳寿命的影响以及最小应力限制等问题。更多还原

【Abstract】 Hydrogenation reactor suffers from the high temperature and cyclic loads in the service,and the effects of creep and fatigue should be taken into account in the design stage.ASME code case 2605 provides a creep fatigue design method for hydrogenation equipment.With the aid of finite element analysis software ABAQUS,a case study of the joint of cylinder and nozzle of a hydrogenation reactor is introduced to conduct creep fatigue design evaluation based on the new edition code case 2605.Some key issues are investigated,such as the method for generating fatigue design curve,the design of reactors that exceed standard cycle times,the effects of design factors and the limit of minimum stress.更多还原
