Based　on　the　concept　of　component　assembly,　a　novel　star　polygon-coupled　honeycomb　metamaterial,　which　achieves　a　collaborative　improvement　in　load-bearing　capacity　and　vibration　suppression　performance,　is　proposed　based　on　a　common　polygonal　structure.　The　compression　simulation　and　experiment　results　show　that　the　load-bearing　capacity　of　the　proposed　metamaterial　is　three　times　more　than　that　of　the　initial　metamaterial.　Additionally,　metal　pins　are　attached　and　particle　damping　is　applied　to　the　metamaterial　to　regulate　its　bandgap　properties;　the　influence　of　configuration　parameters,　including　the　size,　number,　position,　and　material　of　the　metal　pins,　on　bandgaps　is　also　investigated.　The　results　show　that　the　bandgap　of　the　proposed　metamaterial　can　be　conveniently　and　effectively　regulated　by　adjusting　the　parameters　and　can　effectively　suppress　vibrations　in　the　corresponding　frequency　band.　Particle　damping　can　be　used　to　continuously　adjust　the　frequency　of　the　bandgap　and　further　enhance　the　vibration　suppression　capacity　of　the　metamaterial　in　other　frequency　bands.　This　paper　provides　a　reference　for　the　design　and　optimization　of　metamaterials.
