摘要

法兰连接系统的密封性难以通过实验测量，通过有限元模拟方法结合JB4732规则[1]，很容易确定法兰系统的密封性。本文以采用液压拉伸法完成紧固工作的DNIOO、PN63颈对接焊管法兰系统为研究对象。以液压张紧法完成后压力传感器测得的螺栓残余力作为预紧力，利用ANSYS Workbench有限元分析软件，根据JB4732对液压张紧试验后的法兰强度、螺栓强度和垫片密封性能进行了评价，结果表明法兰系统的密封性能良好。

Finite Element Analysis of Flange System Compactness

The tightness of the flange connection system is difficult to measure by experiment, and through the finite element simulation method coupled with the JB4732 rule [1], it is easy to determine the sealing of the flange system. This paper takes the DNIOO, PN63 necked butt welded pipe flange system that uses the hydraulic stretching method to complete the fastening work as the research object. Taking the residual force of the bolt measured by the pressure sensor after the hydraulic tensioning method is completed as the pre-tightening force, using the ANSYS Workbench finite element analysis software, According to JB4732, the strength of the flange, the bolt and the sealing performance of the gasket after the hydraulic tension tightening test are evaluated, and the results show that the sealing performance of the flange system is good.
