| 摘 要： | 根据"钢制压力容器分析设计标准(JB 4732-1995)"规定的应力评定准则,分别建立传统采用的"路径1"和标准《压力容器》(GB 150-2011)推荐的"路径2"两条路径,采用有限元分析方法对直径1 000~3 000mm的容器(具有直径100~1 000mm开孔)进行接管壁厚的设计,并将采用"应力分析方法"得到的结果与采用"等面积法"的计算结果进行了对比。分析结果表明,等面积法较之传统采用的"路径1"偏于危险,但较之GB 150-2011推荐的"路径2"则偏于保守,根据实践经验和有限元分析结果,认为按照"路径2"进行设计更加符合实际情况。 |

| Abstract: | According to stress assessment methods in the standard of steel pressure vessel-design by stress analysis （JB 4732-1995）,two paths were constructed,including a traditional path1 and a path2 recommended by pressure vessel GB 150-2011,and the minimum thickness of the nozzles for openings with a diameter of 100～ 1 000 mm on cylinders with a diameter of 1 000～3 000 mm was designed by using finite element method （FEM）.The analysis result was compared with that from area replacement method.The result shows that the area replacement method is danger than the traditional path1,but a little more conservative than the path2 appealed by GB 150-2011.According to the practice experiences and the finite element results,the path2 is more suitable to practical situation. |
