摘要

杠杆放大机构结构简单、易于实现

但位移传递率较低

输出位移较小。针对以上问题

设计一种基于杠杆放大原理的非对称微夹钳。首先通过几何关系计算出理论输入变量与理论输出变量之间的关系;然后利用有限元分析得出微夹钳的性能

最后通过应变关系找出传感器的最佳安装位置。在输入端施加20μm输入位移

微夹钳的输出位移为221.24μm

位移放大率为11.062。与同类微夹钳相比

具有较大的输出位移。

Abstract

Aiming at the problems

that lever amplifier mechanism is simple in structure and easy to realize

but its displacement transfer rate is low and its output displacement is small

an asymmetric micro-clamp based on lever amplification principle is designed.Firstly

the relationship between theoretical input variables and theoretical output variables is calculated by geometric relationship.Then

the performance of the micro-clamp is obtained by finite element analysis.Finally

the optimal installation position of the sensor is found by strain relationship.The output displacement of the micro-clamp is 221.24 μm and the magnification of the displacement is 11.062 when the input displacement of input end is 20 μm.Compared with similar micro-clamps

the output displacement is larger.
