微动工作台中双平行弹性铰链的结构设计

Design for a Double Parallel Four-bar Flexure Hinge Mechanism in Micropositioner

弹性铰链结构是微动工作台的核心部件。提出了双平行弹性铰链结构设计的要求和设计原则;在满足双平行弹性铰链的刚度、输出位移、应力、弹性恢复力及固有频率等条件下,运用理论与有限元分析的方法对双平行弹性铰链结构设计进行了研究。

Flexure hinge is an essential component of micropositioner. In this paper , The requirement and principle of the struc-ture design for double parallel four-bar flexure hinge mechanism were put forth . Under the circumstances thai the stiffness, output dis-placement, maximum stress, restoring forces and natural frequency meet design requirement , the structure design for double parallel four-bar flexure hinge mechanism are studied by using theory and finite element method .
