【摘要】 文章用有限元方法计算了在工况条件下 ,加氢裂化反应器壁内 ,尤其是某些事故“潜伏”区 ,如埋藏裂纹、截面突变区等的应力分布 .结果表明 :只要反应器内壁无开放性裂纹 ,设备运行是安全的更多还原

【Abstract】 This paper calculated, using limited element analysis, the stress distribution of the add\|hydrogen reactor wall, especially in some accident potential regions such as hidden crack, sudden change section etc. The results show that without open crack in reactor’s inside wall the operation of reactor is safe.更多还原
