| 压力容器接管区域应力场的获得是压力容器强度分析和结构设计的基础。本文采用实验研究的方法,对压力容器斜接管区域的应力状态进行分析研究。根据实验研究的目的,按照工程设计标准设计、制造了一台大型带有两个斜接管压力容器的实验模型,进行了实验方案设计,采用电测法进行了容器斜接管区域的应力测试,在实验数据科学、合理处理的基础上,获得了容器斜接管区域的应力状态和分布规律。实验研究结果表明,容器斜接管锐角侧、钝角侧和相贯线最低点都存在着较大的局部应力,且锐角侧的局部应力数值最大,但是相贯线上的局部应力影响范围较小。 |

| Understanding the stress field in the junction area of pressure vessel body and nozzle is the basis of vessel strength analysis and structure design. This article experimentally studies and analyzes the stress field in the junction area of pressure vessel and nozzle. According to industrial design standard, a cylindrical vessel model with two oblique nozzles was designed and manufactured. In experiment, the stress in the junction area of this model was tested by using electrometric stress-test method. The stress state and distribution in the junction area were obtained based on the experimental data. Results show that there are relatively high local stress on the acute angle side, obtuse angle side, and the lowest points of intersection line, respectively, but the effecting area of local stress on intersection line is small. |
