Space　masts　are　widely　used　in　the　aerospace　engineering　as　one　type　of　deployable　space　structures.　In　this　paper,　based　on　the　stimuli-responsive　effects　of　shape-memory　polymers　(SMPs),　an　intelligent　mast　with　shape-memory　function　is　studied.　The　thermos-mechanical　constitutive　model　of　SMPs　is　associated　with　the　finite　element　(FE)　software,　and　then　the　deployable　deformation　and　shape-memory　effect　of　the　intelligent　mast　are　investigated　by　the　FE　method.　It　is　demonstrated　that　the　mast　can　automatically　deploy　due　to　the　shape　recovery　characteristics　of　SMPs.　Furthermore,　the　effects　of　structure　parametric　of　the　mast　and　temperature　are　also　investigated.　The　results　can　contribute　to　the　design　and　application　of　novel　SMP　masts.　[GRAPHICS]　.
