Abstract：

This　paper　studies　the　equivalent　modeling　method　of　truss　cell　elements　with　clearance　joints.　The　equivalent　stillness　and　damping　problem　of　unit　cell　truss　are　mainly　considered.　Firstly,　a　comprehensive　hinge　gap　model　is　constructed　by　considering　on　the　gap　hinge.　An　equivalent　method　is　then　put　forward　to　simplify　the　truss　unit　cell　to　a　plate-like　structure.　As　structural　element　is　assumed　as　a　steel　beam,　the　displacement　method　is　used　to　get　the　equivalent　stillness　matrix　of　plane　truss　unit　cell　in　different　boundary　condition.　The　overall　natural　frequency　and　plate　equivalent　stiffness　matrix　after　equivalence　are　then　obtained.　Finally,　finite　element　analysis　(FEM)　by　a　software　of　ANSYS　is　proposed　for　structural　modal　analysis　of　the　structure　with　clearance　joint.　The　results　show　that　when　the　stiffness　of　the　truss　structure　unit　cell　is　reduced,　the　flexibility　is　increased.　©　2018　Journal　of　Dynamics　and　Control.　All　rights　reserved.
