摘要
Abstract
GB 150 can only calculate the pressure vessel subjected to internal pressure and external pres-sure,it does not involve the complex moments exposed to the actual end surface of nozzles. The research object of this paper is the cylindrical circumferential opening tubing structure. Using three-dimensional solid finite element method,utilizing the ANSYS software,under internal pressure and complex moments, the stress analysis and strength assessment were done. The analysis results indicate that the intensity re-quirement can be satisfied and it can be used safely. In addition,comparing with the situation of under in-ternal pressure,it is hoped that it can investigate the effects of the composite moments on the opening takeover.关键词
