摘　　要：针对设计的压力管道上使用的大尺寸非标准八角垫圈法兰,根据Waters法兰设计准则,采用有限元方法校核了法兰和螺栓的强度及垫片的密封性。结果表明,所设计的非标准法兰满足设计要求,有限元分析方法有效、可靠。Large non-standard octagon gasket flange used on the pressure pipeline is designed. Finite element analysis for the strength of the parts and sealing performance of the gasket are discussed based on Waters-design rule. The results showed that the design of the non standard flange is meeting required. Finite element analysis is an effective and reliable method for the de sign of flange.
