摘要

研究了设计尺寸变量对采用桥式放大柔性铰链的二自由度工作平台位移的影响。采用INVENTOR软件对机构进行建模，并在ANSYS中采用有限元法计算机构的输出位移(DI)。有限元分析结果表明，柔性铰链厚度对机构位移的影响较大，输入体长度对模型x、y两轴方向位移的影响较大。在输入位移为0.01的情况下，x、y方向位移最大达到0.683 mm，放大68.3倍。这个值比之前的投资要高。

Analytical effects of design parameters on displacement of 2-DOF working platform employing bridge-type amplifier flexure hinge by finite element method

The paper investigated effects of design dimension variables on displacement of a 2-DOF working platform employing bridge-type amplifier flexure hinge (BTAFH). The mechanism was created by the INVENTOR software and then obtained the output displacement (DI) by finite element method (FEM) in ANSYS. The FEM result indicated that thickness of flexure hinge (TOFH) strong impact on displacement of the mechanism and input body length contributed rising displacement according two axis x and y direction of the proposed model. The maximum value of displacement achieved 0.683 mm according x and y direction with input displacement of 0.01 amplified 68.3 times. This value is higher than the previous invest igatio n.
