In　order　to　solve　the　problems　of　low-profile　accuracy　and　poor　control　stability　of　the　satellite　antenna　due　to　axial　coupling　vibration,　in　this　paper,　a　self-resetting　friction　damper　is　proposed　to　suppress　axial　vibration.　Firstly,　a　self-resetting　friction　damper,　with　a　lightweight,　wide　frequency　band,　and　high　energy　consumption,　is　designed.　The　principle　of　dry　friction　energy　loss　of　metal　rubber　(MR)　and　the　effect　of　self-resetting　of　shape　memory　alloy　(SMA)　are　used.　Secondly,　the　vibration　reduction　mechanism　model　of　the　self-resetting　friction　damper　is　established,　and　the　principle　of　damping　energy　dissipation　is　analysed.　Finally,　sinusoidal　excitation　tests　of　the　components　of　the　satellite　antennas　with　self-resetting　friction　dampers　are　carried　out.　The　axial　vibration　loss　factor　of　the　components　of　the　satellite　antenna　with　the　self-resetting　friction　damper　is　calculated,　and　the　vibration　resistance　performance　of　the　damper　is　verified.　Theoretical　analysis　and　experimental　results　show　that　the　self-resetting　friction　damper　has　a　significant　effect　on　suppressing　the　axial　vibration　of　the　components　of　the　satellite　antenna.　It　is　feasible　to　install　a　self-resetting　friction　damper　in　the　components　of　the　satellite　antenna　to　suppress　the　axial　vibration.　©　Published　under　licence　by　IOP　Publishing　Ltd.
