【摘要】 讨论了一种平面3自由度柔性并联微动工作台的运动情况。首先建立了机构的两个闭合回路,简化了Y.Yong,T.Lu和D.Handley[3]提出的3条闭合回路的模型。再根据“伪刚体模型”法建立方程,从而得到各柔性铰链的旋转角度及机构的运动情况。最后根据齐次坐标变换得到机构运动输入与输出关系,有助于得到机构的运动空间和范围。更多还原

【Abstract】 In this paper we consider the kinematics modeling of a three-degree of freedom planar micro- motion stage using flexure hinges. The kinematics analysis of this stage is based on the closure loop theory and pseudo-rigid-body model. We gain the deflection angle of every flexure hinges through a series of equations and the relationship of the input and output will be found.更多还原
