A　design　method　to　enhance　both　mechanical　and　vibrational　isolation　properties　of　honeycomb　meta-material　is　proposed　and　verified　by　a　proposed　in-folded　hexagonal　honeycomb　meta-material　(I-HHM).　Based　on　the　traditional　hexagonal　honeycomb　structure　(T-HHM),　the　I-HHM　is　designed　with　in-folded　bars　instead　of　straight　bars　and　rings　at　the　joints,　and　metal　pins　are　inserted　into　the　rings.　The　mechanical　and　vibrational　suppression　performance　of　the　I-HHM　is　analyzed　by　finite　element　method　and　experiment.　The　results　show　that　compared　with　the　T-HHM,　the　I-HHM　has　greater　advantages　in　load-bearing　capacity　and　stiffness,　and　has　wider　bandgaps.　In　addition,　according　to　the　concept　of　assembly,　the　combination　of　particle　damping　and　rings　can　direct　vibration　energy　to　the　local　structure　for　consumption,　which　further　enhances　the　vibration　reduction　and　customization　capabilities　of　the　I-HHM.　The　proposed　method　provides　a　feasible　way　for　the　optimization　of　meta-materials.
