具有柔性铰链的柔性机构由于其平滑和可重复的运动而非常适合于高精度应用。然而，由于缺乏一定的多轴柔性铰链，基于切口柔性铰链的平面柔性机构的综合大多局限于单轴柔性铰链的使用。本文提出了一种基于圆形预弯板簧的具有两个重合转动轴的平面叶片型缺口柔性铰链。通过使用有限元法（FEM）的参数研究来确定通常合适的铰链几何形状。最后，双轴柔性铰链的应用和研究，用于两个平面微定位平台的直线导向的输出连杆与一个大厘米行程。提出的双轴柔性铰链是一种实现柔性机构三杆件平面精确连接的合适方法。
Compliant mechanisms with flexure hinges are well-suited for high-precision applications due to their smooth and repeatable motion. However, the synthesis of planar compliant mechanisms based on notch flexure hinges is mostly limited to the use of single-axis hinges due to the lack of certain multiple-axis flexure hinges. This contribution introduces a novel planar leaf-type notch flexure hinge with two coincident rotation axes based on circular pre-curved leaf springs. A generally suitable hinge geometry is determined through a parametric study using the finite element method (FEM). Finally, the two-axis flexure hinge is applied and investigated for the use in two planar micropositioning stages for the rectilinear guidance of an output link with a large centimeter stroke. The presented two-axis flexure hinge turns out to be a suitable approach to monolithically connect three links of a compliant mechanism in a planar and precise way.
