采用电测法对内压作用下支管与主管轴线夹角为30°的安放式斜接管结构模型进行了试验研究,获得了接管-筒体截交区的应力分布规律和最大应力值及其出现的位置,进而得到了该模型的应力集中系数,这些数据可作为斜接管结构设计和制造的参考。
The model of the miter tube structure with the included angle of 30 ° between the branch tube and the main tube under the action of internal pressure was tested by electrical method. The stress distribution and the maximum stress value of the tube - Then, the stress concentration factor of the model is obtained, which can be used as a reference for the design and manufacture of the miter tube structure.
