摘要：

To　obtain　the　initial　imperfections　sensitivities　of　the　tape-spring,　and　thus　improve　the　stability　of　the　space　deployable　hinge,　a　model　with　eigenvalue-buckling-mode　imperfection　was　established　by　the　finite　element　software　Abaqus.　The　influence　of　the　orders　and　the　factors　of　the　eigenvalue-buckling-mode　as　variables　on　the　mechanical　behaviors　in　the　pure-bending　process　of　the　tape-spring　were　investigated.　Results　show　that　the　tape-spring　is　more　sensitive　to　the　eigenvalue-buckling-mode　imperfection　in　positive　bending.　The　eigenvalue-buckling-mode　imperfection　has　a　smaller　effect　on　the　driving　force,　but　has　a　bigger　influence　on　the　self-locking　ability　of　the　tape-spring.　This　research　is　useful　to　complement　and　perfect　the　analysis　on　the　tape-spring　stability.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
