摘要: 基于长柔性杆设计了一种新的微位移放大机构结构形式,根据推导出的力-位移关系及放大比关系分析了机构主要性能与机构参数的关系.通过一组实例的理论计算与有限元仿真,分析得到该机构主要结构参数对机构性能的不同影响效果.

Abstract: A model of amplification mechanisms was designed on the basis of long-length flexure beams.According to the force-deflection relationship and the amplification ratio derived from analytical method,a parametric study on mechanism performances was carried out.The effects of the key structural parameters of the mechanisms on the mechanism performances were identified by theoretical calculation and finite element simulation of a set of examples.
