摘要：

When　FEM　is　used　to　analyze　the　structures　that　include　plate-like　joint　interfaces,　the　effect　of　plates　on　joint　interfaces　is　often　be　ignored　and　defect　thus　follows.　Aiming　at　the　traditional　method　for　calculating　the　stiffness　of　plate-like　joint,　this　defect　is　revised　and　a　comprehensive　unit　stiffness　matrix　is　deduced.　The　matrix　can　be　applied　to　finite　element　analysis　and　identities　of　dynamic　characteristic　parameters　of　joint　interfaces.　By　comparing　the　results　of　presented　method　and　the　traditional　method　through　an　example,　the　former　is　proven　to　have　higher　accuracy　and　reliability.　The　presented　method　can　be　applied　to　modeling　and　analyzing　of　the　similar　structure　and　can　be　used　as　a　way　to　solve　mechanical　vibration　issues.　©,　2014,　Beijing　University　of　Technology.　All　right　reserved.
