【摘要】 采用有限元法对加氢反应器h型锻件与筒体、封头及裙座连接区进行了机械应力与温度应力分析 ,并对关键位置进行了应力评定 ,发现h型锻件与裙座连接侧的厚度不能仅根据JB4 710—1992《钢制塔式容器》确定的裙座厚度决定 ,而应按分析设计的观点进行应力分析 ,以充分考虑h型锻件与裙座间变形协调所引起的边缘应力及温度应力 ,进而确定h型锻件与裙座连接侧的合理厚度。更多还原

【Abstract】 Mechanical and thermal stresses were analyzed and assessed with FEM for the connecting region of h-type forge piece to cylinder,spherical head and skirt in the hydrogenation reactor. It was founded that the connecting thickness of the h-type forge piece to the skirt is not reasonable if it is only determined by the skirt thickness deduced from the code JB4710-1992“Steel tower vessel”. The reasonable connecting thickness should be based on further stress analysis and assess,in which boundary stress from displacement agreement and thermal stress may be fully considered.更多还原
