Abstract

This paper proposes a three-degree-of-freedom (3-DOF) high-precision stick-slip platform with planar parallel decoupling and backward inhibition. An arch driving unit using macro fiber composite (MFC) is proposed to realize large single-step output and actuation-structure integration, and pillar support is devised to improve load capacity. A cooperative driving method is designed to suppress backward movement. Then, a system dynamics model with electromechanical, friction, and the 3-DOF connection is established. Finally, a prototype is manufactured, and various experiments are conducted. The proposed stick-slip platform exhibits large single-step displacements of 301.6 μm, 292.9 μm, and 9.947 mrad for the X-axis, Y-axis, and rotation around the Z-axis motion, respectively. The maximum vertical load is 110 N. Also, the backward rate is reduced from 62.9 % to 0.56 % for translational movement in the X and Y axes and from 46.8 % to 2.79 % for the Z-axis rotation. Thus, experiments verify the proposed stick-slip platform with macro fiber composite.

基于宏纤维复合材料的新型三自由度平面平行粘滑平台

提出了一种具有平面并联解耦和后向抑制的三自由度高精度粘滑平台。提出了一种采用宏纤维复合材料（MFC）的拱驱动单元，实现了大单步输出和驱动结构一体化，并设计了支柱支撑，提高了承载能力。设计了一种抑制向后运动的协同驾驶方法。然后，建立了机电、摩擦和三自由度连接的系统动力学模型。最后，制作了样机，并进行了各种实验。该粘滑平台在x轴、y轴和绕z轴旋转方向上的单步位移分别为301.6 μm、292.9 μm和9.947 μ ad。最大垂直载荷为110 n，在X轴和Y轴的平移运动中，倒向率从62.9%降低到0.56%，在z轴旋转中从46.8%降低到2.79%。因此，实验验证了所提出的宏观纤维复合材料粘滑平台。
