摘　　要：提出了一种新型柔性铰链——单边直圆导角复合柔性铰链,以卡氏第二定理为理论基础,推导了单边直圆导角复合型柔性铰链的柔度计算式.利用所得结果对实例进行柔度的理论计算,同时对其作限元分析,通过结果对比,验证了柔度计算式的正确性.同时对单边直圆导角复合柔性铰链的性能进行分析,分析了结构参数对其柔度性能的影响,通过与双边直圆导角复合柔性铰链比较,得出了单边直圆导角复合柔性铰链的转动能力、对载荷的敏感性均优于双边直圆导角复合柔性铰链,为柔性铰链在结构紧凑、大位移场合的工程应用提供了新的思路.A novel flexure hinge--half hybrid flexure hinge with right circular corner was presented. Based on Castigliano＇s second theorem, compliance equations of the novel flexure hinge were formulated. Theoretical calculation and finite element simulation of some illustration were conducted simultaneously; the similar results were obtained which demonstrated the validity of the compliance equations. Furthermore, the performance of half right circular corner filleted flexure hinge was analyzed, including the effect of its geometric parameters on its performance. Compared with symmetrical right circular corner filleted flexure hinge, the compliance and sensitivity to the load of half right circular corner filleted flexure hinge were better than those of symmetric right circular corner filleted flexure hinge. The above results provide a new idea for the applications of flexure hinge, which is used in compact structure and structure with large displacement.
