To　solve　the　problem　that　the　traditional　friction　damper　has　high　demand　for　positive　pressure　and　unstable　hysteresis　performance　when　providing　large　damping　force,　a　new　type　of　cylinder　laminated　friction　damper　was　proposed.　The　wedge-shaped　entity　can　amplify　the　positive　pressure　required　by　the　friction　surface,　and　the　circumferential　restriction　of　the　cylinder　can　de　used　to　improve　the　pressurization　efficiency　of　the　damper.　Based　on　the　principle　of　lamination,　the　positive　pressure　provided　by　the　central　pressure　device　can　be　applied　to　multiple　friction　surfaces　at　the　same　time.　The　non-asbestos　composite　resin　friction　sheet　with　more　stable　friction　performance　was　used　as　the　friction　material　of　the　damper　to　avoid　the　problem　of　unstable　friction　performance　of　the　traditional　metal　friction　surface　after　several　cycles.　The　theoretical　formula　of　the　damping　force　was　deduced,　and　the　influence　of　each　structural　parameter　on　the　output　of　the　damper　was　obtained.　The　hysteretic　performance　and　shock　absorption　effect　were　analyzed　through　mechanical　performance　test　and　numerical　simulations.　Results　show　that　the　damper　has　stable　hysteretic　performance,　excellent　fatigue　resistance,　good　energy　dissipation　performance,　and　good　shock　absorption　effect　on　the　actual　structure.　©　2022,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
