提出了一种新型的压电直线精密步进驱动器。该驱动器采用步进仿生运动的原理(Pusher)
以定子箝位和定子驱动的方式实现动子被动运动。在对驱动器工作原理和机械结构分析的基础上
建立以压电叠堆为驱动元件的直线驱动数学模型
并对其结构进行了有限元分析。这种驱动器采用双向推力的结构原理
实现了在正反向与运动过程中驱动特性的一致。实验证明
以这种新型驱动方式构造的驱动器实现了箝位牢固、高频率(100 Hz)驱动、高步进速度(30 mm/min)、大行程(>10 mm)、高分辨率(0.05 m)、大驱动力(100 N)等特点
大幅度提高了压电型步进驱动器的驱动性能
在精密运动、微操作、光学工程、精密定位等精密工程中有广阔的应用前景。
