Comparative analysis of parabolic and hyperbolic flexure hinges using closed-form equations

摘要：

　　The comparative analysis of a parabolic and hyperbolic flexible hinges were presented.The closed-form compliance equations in the working and non-working plane can be derived by using the Castiglianos second theorem.In order to compare the relative performance of parabolic and hyperbolic flexure hinges,a ratio function between specific compliances of the two hinges is defined.We analyzed the non-dimensional ratios of working plane and non-working plane compliance to show the relative properties of parabolic versus hyperbolic flexure hinges.The analysis results has showed compared to a hyperbolic flexure,a parabolic flexure can produce more desired output and is slightly less sensitive to axial effects under identical loading conditions.Meanwhile,the comparative study on the parabolic and hyperbolic flexure hinges can provide a theoretical basis for choosing them.
