Fundamental　frequency　vibrations　generated　by　aero-engines　can　propagate　through　joint　structures　to　the　airframe,　potentially　causing　significant　damage　to　precision　instruments　and　electronic　equipment.　This　paper　innovatively　integrates　the　spiral　resonant　system　(elastic　wave　manipulation　capability)　into　the　Hierarchical　Diamond　Honeycomb　with　Variable　wall　Thickness　(HDH-VT)　structure　(lightweight　and　high-strength　mechanical　properties),　designing　a　Locally　Resonant　Metamaterials-　Bolted　Joints　(LRMs-BJ)　to　suppress　the　transmission　of　harmful　vibrations　from　aero-engines　to　the　airframe.　First,　an　equivalent　model　of　the　spiral　resonant　system　is　developed,　with　a　detailed　analysis　of　the　vibration　reduction　mechanism　of　the　flexural　wave　bandgap　and　its　tuning　capabilities.　Second,　the　vibration　reduction　characteristics　of　LRMs-BJs　are　investigated　through　finite　element　simulations　and　experiments,　and　the　effects　of　various　joint　conditions　on　the　vibration　reduction　frequency　band　of　LRMs-BJs　are　analyzed.　The　results　demonstrate　that　the　spiral　resonant　system　can　produce　bandgaps　within　the　target　frequency　range,　and　modifying　the　structural　parameters　of　the　spiral　elastic　beam　enables　flexible　low-frequency　tuning　of　the　bandgap.　The　LRMs-BJ　exhibits　significant　vibration　control　within　the　vibration　reduction　frequency　range.　The　effects　of　lap　length,　bolt　arrangement　direction,　and　preload　on　the　position　and　width　of　the　vibration　reduction　band　are　minimal,　closely　aligning　with　the　bandgap　of　the　spiral　resonant　system　unit　cell.　The　proposed　LRMs-BJ　is　a　multifunctional　integration　of　metamaterials　and　honeycomb　structures,　broadening　the　application　potential　of　metamaterials　in　vibration　reduction　for　bolted　joints.
