摘要

提出了一种等腰梯形压电黏滑直线驱动器

通过粘贴在等腰梯形柔性机构柔性斜梁两侧的4片矩形压电陶瓷片使驱动足驱动滑块

以达到基于黏滑运动的高分辨率和大行程线性运动。调整等腰梯形柔顺机构斜梁的角度

可使驱动足产生横向运动

基于有限元方法

获得了柔性梁的适当角度。通过等腰梯形柔性铰链驱动足的横向运动

可增加使滑块前进的静摩擦力

减少回退动摩擦力。搭建了试验测试系统并进行了一系列试验

结果表明

该样机在4 N锁定力下最大输出速度为601.803μm/s

最大输出力为2.8 N

最小步进距离为0.026μm。采用压电陶瓷片作驱动源

易于小型化

拓宽了压电陶瓷片的应用领域。
