提出了一种新型的双平行四连杆柔性铰链弹性导向结构,用作石英力传感器的力导向元件.这种采用柔性铰链连接双平行四连杆形成单方向位移的弹性导向机构,有着优良的机械性能:无机械摩擦,无间隙,运动灵敏度高,导向精度高,能自动消除偏载影响.文中对其在正常载荷及偏载下的响应进行了详细讨论,给出了导向位移及偏移误差和采用这种结构的石英力传感器的应用结果.“,”This paper introduces a new type of elastic guiding mechanism developed for quartz force sensor It consists of parallel quad crank arms connected by flexible hinges.This paper analyzes and calculates the deformation of this mechanism under the normal force and the deviation load.Both the theoretical analysis and the application results show that the guiding mechanism has fast and linear response in motion direction and no shift motion in ...
