| 摘 要： | 设计出一种新型多轴柔性铰链--直圆导角复合型多轴柔性铰链，以卡氏第二定理为理论基础，推导了柔度计算式。利用所得结果进行实例计算，并进行有限元分析，通过结果对比验证了计算式的正确性。定义了铰链的厚长比λ，分析了柔度相对误差与λ之间的关系。利用所得柔度计算式，分析了铰链结构参数对其柔度的影响。通过与直圆型多轴柔性铰链的对比，得出直圆导角复合型多轴柔性铰链的转动能力与对载荷的敏感性均优于前者的结论。

| Abstract: | A novel multiple-axis flexure hinge-right circular corner-filleted hybrid multiple-axis flexure hinge was presented.Based on Castigliano's second theorem，compliance formulas were formulated.Compliance calculations and finite element simulation were performed simultaneously for a sets of examples.By contrast to the results，correctness of the compliance formulas were verified.The ratio [λ] named as thickness-length ratio was defined，and the relation between the compliance errors and [λ] were analyzed.By means of the compliance formulas，the effects of the structural parameters on the compliance were analyzed.Compared with the right-circlar multiple-axis flexure hinges，compliance and sensitivity to the load of the novel hybrid multiple-axis flexure hinge are better than those of the right-circlar multiple-axis flexure hinge. |
