Abstract：

Vibration　control　of　flexible　deployable　mechanism　is　seriously　significant　with　the　increasing　application　of　it　in　aerospace　field.　Satellite　antenna　must　be　carried　out　in　folded　state　due　to　small　space　of　launch　vehicle.　In　the　process　of　deployment　and　attitude　adjustment,　vibration　has　a　great　influence　on　the　contour　accuracy.　Based　on　transfer　matrix　method,　the　deployment　structure　of　large　flexible　deployable　satellite　antenna　is　analysed　to　obtain　its　natural　frequencies　and　modes.　By　solving　the　first　three　natural　frequencies　and　modes　in　different　deployment　angles,　the　structure　completely　deployed　is　prone　to　be　coupled　and　has　the　worst　stability.　Thus,　damping　structure　to　suppress　vibration　at　all　modal　resonance　points　of　fully　deployed　satellite　antenna　is　necessarily　to　be　installed.　A　new-type　damping　structure,　multi-petal　friction　damping　structure　with　the　characteristics　of　simple　structure　and　wide　frequency-band,　is　proposed　in　previous　paper.　The　dynamic　analysis　of　deployment　process　at　different　angles　for　deployment　component　with　damping　structure　is　carried　out　to　verify　the　damping　effect　and　the　feasibility　of　damping　structure　as　well　as　the　rationality　of　theoretical　analysis.　©　Published　under　licence　by　IOP　Publishing　Ltd.
