Finite Element Analysis of Bolted Flanged Joints Subjected to External Loads

摘要：

　　Since external loads affect the sealing performance of bolted flanged joints, this paper calculated external loads of bolted flanged joints by using CAESAR Ⅱ software and evaluated the effects of external loads on the sealing performance from the viewpoint of changes in contact gasket stress and flange rotation by using ANSYS software.The FE results showed that the contact gasket stress decreases a lot at the tension side and increases a little at the compression side.The paper also evaluated the stress distribution in bolted flanged joints subjected to external loads.The results suggested that the flange rotation and the overall stress increased compared with that of flange without external loads.External loads can induce unexpected leakage and strength failure of the bolted flanged joints during operation.
