摘要

Compliant mechanism flexure hinge was frequently utilized in precision enginering in recently years such as bridge-type and rhombus-type compliant mechanism. The previous study used approximation mathematic model to estimate displacement amplification ratio. But the result of this investigations obtain displacement amplification ratio aproximatly 30. It identify so difficult to obtain maximum and precision value. Therefore, in this paper designed new model for bridge-type compliant flexure in SOLIDWORK. Displacment amplification ratio was calculated by using finite element method in ANSYS. The simualtion result reveal that ouput displacement increase from 0.506 mm to 0.648 mm when length of input body increase from 5 mm to 15 mm with thickness of flexure hinge of 0.3 mm and input displacement of 0.01 mm. The displacement amplification obtained from 50.6 to 64.8. concentration stress increase from 78.7 MPa to 101.5 MPa. Moreover, input incline angle between two flexure changes from 1.2 degree to 1.6 degree, with length of input body of 5 mm and the input displacement of 0.01 mm, output displacemt increases from 0.505 mm to 0.521 mm. The displacement amplification ratio obtained from 50.5 to 52.1 and concentration stress increased from 78.7 MPa to 80.16 MPa and then reduce to 74.19 MPa. The length of input body has significant effected while the incline angle between two flexure hinge from 1.2 degree to 1.6 degree has slightly effected on the displacement amplification of bridge-type compliant mechanism.
