介绍了微动工作台中弹性板簧导轨的设计方法、特性误差的计算 ,重点叙述了载荷反对称布置的弹性导轨使微动台产生独立转动自由度的方法 .与以柔性铰链为主体的平面三自由度微动工作台相比 ,弹性板簧导轨式的微动工作台力学模型简单 ,无原理误差 ,从而提高了工作台的位移精度 ,避免工作台在各运动方向之间的耦合 .在板簧上粘贴应变片还可以测出微动台的位移 ,简化了测量系统 . The design method and characteristic error of the elastic leaf spring guide rail in the fretting workbench are introduced, and the method of independent rotation of the microlensing platform with elastic guide rail with anti-symmetrical load is emphatically described. Compared with the fretting fretting table, the mechanical model of the fretting table with elastic leaf spring guideway is simple and has no principle error, thereby improving the displacement accuracy of the working table and avoiding the coupling of the working table in each motion direction. Sprung pasting strain gauges can also be measured micro-displacement, simplifying the measurement system.
