摘　　要：凸缘是压力容器开口的主要补强元件 ,常被应用于易燃易爆、高压、高温、低温、厚壁压力容器、要求疲劳分析的压力容器、盛装极度或高度危害介质的压力容器等重要场合。经过多方案的比较计算 ,优选出一些结构尺寸和角度值 ,最终筛选出三种凸缘结构形式 ,解决了设计中小直径接管凸缘计算通不过、大直径接管凸缘或人孔凸缘尺寸过大的弊病 ,按照本文提供的方法 ,设计者只要经过最多两种结构的比较计算 ,就能得到既满足补强要求。The integrated forging reinforcements was an important reinforcement part of pressure vessel openings,and it ,s usually applied to pressure vessels of containing flammable?explosible?high pressure?high temperature?low temperature and thick wall?requested fatigue analyses?containing extremity or high endanger medium etc.Author optimized several structuresd dimension and angle values,and finally selected the three structures of integrated forging reinforcements after author had comparatively calculated many cases.It settled the disadvantages which small diameter nozzles can ,t calculated according with codes to meet requirement and the integrated forging reinforcement dimension of big diameter nozzles or manhole were too big in past desining.According to the method offered in this text,designer could gain integrated forging reinforcement result of optimization design that not only meeting reinforcing requirement but also diminishing structure dimensions.
