FEA of the Effect on Anti-slippery Performance of the Frictional High-Strength Bolt Caused by Gasket

The simplified model connected by the high-strength bolts was established by making use of the ANSYS 9.0 software.The anti-slippery performances of the M20 frictional high-strength bolts,which had the various-size gaskets,were carried out by the nonlinear analysis.Moreover,the ANSYS digital results with the various-size gaskets were dealt with the comparative research.These indicate that the various-size gaskets have some influence on the anti-slippery performances of the frictional high-strength bolts.Therefore,some significant references to the actual engineering are offered.
