Flexible　microporous　metal　rubber　(FMP-MR)　is　a　high-damping　material　that　dissipates　energy　by　dry　friction　through　internal　spiral　metal　wires　in　contact　with　each　other.　However,　the　FMP-MR　energy　dissipation　mechanism　is　not　fully　understood　owing　to　its　disordered　grid　interpenetrating　structure.　In　this　work,　computer-aided　preparation　technology　is　used　to　accurately　reconstruct　the　complex　spiral　network　structure　of　FMP-MR　multipoint　random　contact,　and　a　cell　group　model　with　an　energy　dissipation　mechanism　is　proposed　to　obtain　the　dynamic　energy　distribution　of　the　contact　friction　in　both　space　and　time　dimensions.　By　judging　the　effective　contact　point,　a　global　displacement　ablation　phenomenon　of　hooked　staggered　porous　materials　is　induced.　The　macro-　and　micro-equivalent　frictions　are　introduced　to　effectively　explain　the　characteristics　of　the　strong　energy　dissipation　in　FMP-MR　under　fretting　excitation.　A　real　and　effective　damping　hysteresis　constitutive　model　is　then　constructed　to　dynamically　capture　the　mapping　relationship　between　the　complex　nonlinear　topological　structure　effect　of　the　materials　and　spatial　random　contact　dry　friction　in　real　time.　The　results　indicate　that　the　contact　behavior　between　turns　of　the　FMP-MR　wire　follows　a　clear　quasi-Gaussian　distribution　under　an　external　load,　forcing　the　topological　results　to　change.　The　energy　dissipation　of　the　materials　revealed　peak　energy　consumption　lagging　behind　the　loading　limit　for　a　certain　distance,　which　can　be　determined　by　the　effective　contact　point　and　contact　dry　friction　slip.　The　consistency　between　the　quasi-static　compression　tests　and　constitutive　curves　of　the　model　was　quantitatively　verified　through　residual　analysis.　The　data　demonstrated　the　differential　behavior　of　the　FMP-MR　meso-structure　to　follow　a　phased　growth　law　during　loading　with　different　action　mechanisms　in　the　guiding,　main　growth,　and　relaxation　stages　of　the　energy　consumption　displacement　curve.　In　summary,　these　findings　provide　an　acceptable　theoretical　basis　for　the　damping　energy　consumption　mechanism　and　lifetime　prediction　of　FMP-MR.　©　2022,　The　author(s).
