Abstract：

To　reflect　the　dynamic　features　of　fixed　joint　interfaces,　a　universal　model　of　tangential　contact　stiffness　for　joint　interfaces　was　put　forward　by　using　fractal　theory,　which　was　assumed　by　a　flat　rigid　surface　and　a　deformed　rough　counter-surface　and　in　contact　with　the　elastic　half-space.　The　numerical　simulation　results　indicated　that　the　fixed　joint　interfaces　tangential　contact　stiffness　was　increased　with　normal　load　increasing.　The　nonlinear　and　linear　relationships　were　existed　between　the　fixed　joint　interfaces　tangential　contact　stiffness　and　normal　load　when　1　©,　2015,　CIMS.　All　right　reserved.
