摘　　要：为满足航天可展结构需要,提出了一种大转角柔性铰链,其转动角度可达180°。借助几何运动学理论,进行了大转角柔性铰链的结构设计;并对柔性体的尺寸、啮合曲面轮廓、转动刚度、储存能量等关键问题进行了理论分析。得出了柔性体最小长度、厚度与柔性体转动时的最小弯曲半径之间的关系;给出了啮合面的轮廓计算、铰链的转动刚度、柔性铰链储存能量的计算解析表达式。这一柔性铰链的提出及关键问题的解决为相关领域的研究应用提供了重要的参考。To meet the need of deployable structures for space, a flexible hinge with a large turn angle of approximately 180 degrees is presented. The structure of the flexible hinge is designed on the basis of geometry and kinematics principle. Such key problems as dimension of flexible hinge, mesh figure, torsion stiffness and stored energy are theoretically analyzed. The analytical solution to these problems is given. The flexible hinge can be used in design of deployable structures for space and other special fields.
