摘　　要：在双叶弹簧基础上设计制作了弹簧钢材料的双悬臂梁弹性敏感元件,并从理论上分析了元件的力学性能。采用有限元分析方法研究了元件受力变形情况,验证了理论分析的准确性和可靠性,最后对元件法向和切向刚度进行了静态标定。结果表明:该元件具有良好的输入输出线性关系;选择性改变悬臂梁的几何参数,可以获得不同灵敏度的弹性敏感元件,可广泛用于各种测微装置。Based on the double leaf spring,a elastic-sensitive element of double cantilever beam was designed and made from spring steel materials,and the mechanical properties of the element was analyzed in theory.After that,finite element analysis method was used to study the force-deformation of the element,and to verify the accuracy and reliability of the theoretical analysis.The static calibration was given for the normal and tangential stiffness of the element.The results showed that the device has a good linear relationship between input and output,and if the geometric parameters of cantilever beam are changed,it can get the elastic-sensitive element with different sensitivity,so it can be widely used in various micrometer devices.
