摘　　要：如何设计大变形的柔性铰链是目前进行柔性铰链研究的方向和热点之一。讨论了几种典型大变形柔性铰链的结构形式及特点,提出了应用多簧片构型设计大变形柔性铰链的参考方法,并根据此方法设计了一种具有较大转动范围的多簧片构型的柔性铰链,应用有限元方法进行了分析及实验研究。实验结果表明,这种多簧片串并联构型的柔性铰链具有较大的转动范围、转动柔度和较小的径向刚度。The traditional prototypes of flexure hinge derived by Paros and Weisbord have the limitation of limited translation or rotation. While in many occasions, the flexure hinges characterized by large range of translation or rotation are needed.Consequently, the designing of new type of flexure hinge which has merits of expanded motion range is becoming the researching focus. Multi-leaf type configuration is one of the resolutions which make the flexure hinges characterized by expanded motion range to be true. A multi-leaf type flexure hinge has been presented in this paper which having larger rotation range analyzed by the Finite Element Method （FEM） and experiment. Optimized with parallel-multi-leaf which have the characterizes of larger rotation range and compliance, while small rotation center shift.
