To　fulfill　the　vibration　damping　requirements　of　plate　structures　under　complex　conditions,　additional　damping　structures　with　entangled　metallic　wire　material　(EMWM)　are　proposed　based　on　the　excellent　physical　properties　of　EMWM.　A　batch　of　specimens　with　different　filament　diameters,　densities,　and　thicknesses　are　prepared.　The　stiffness　and　loss　factors　are　taken　as　the　evaluation　indexes,　and　orthogonal　tests　are　conducted　to　obtain　the　tensile,　shear,　and　compression　properties.　The　results　show　that　the　optimal　parameter　combinations　can　be　obtained　through　orthogonal　tests.　For　the　specimens　with　optimal　parameter　combinations,　the　mechanical　tests　under　different　loading　rates　and　loading　displacements　are　carried　out.　With　the　increase　in　loading　rate,　the　tensile　and　shear　forces　appear　to　display　fracture　failure　in　advance,　and　the　compression　performance　is　stable　without　significant　changes.　The　change　rule　under　each　mechanical　test　is　explored　using　the　stiffness　and　loss　factor　evaluation　index.　It　provides　a　reference　for　the　analysis　of　the　preparation　parameters　of　subsequent　additional　damping　structures　with　EMWM.
