A　novel　coated　damping　structure　for　metal　rubber　(MR)　of　bellows　is　designed　based　on　large-size　metal　rubber　sheets.　This　structure　is　dynamically　tested　in　the　bending　direction　at　normal　temperature.　According　to　the　test　results,　a　model　of　the　nonlinear　elastic　restoring　force　is　set　up,　which　describes　the　dynamic　characteristics　of　the　coated　damping　structure　for　metal　rubber　of　bellows,　and　identifies　the　parameters　of　the　model.　The　results　show　that　the　coated　damping　structure　for　metal　rubber　of　bellows　has　a　strong　damping　energy　dissipation　ability,　its　dynamic　vibration　characteristics　are　related　to　the　vibration　amplitude　and　frequency,　and　it　is　a　complex　nonlinear　hysteretic　system　with　multiple　damping　components.　After　identification　of　the　parameters,　the　model　of　nonlinear　elastic　restoring　force　shows　highly　accurate　results.
