    摘要:

    为利用驱动足椭圆轨迹的改变实现对压电直线电机输出性能的控制,提出并设计了一种基于复合放大机构的压电直线电机。电机驱动足由三角机构和杠杆机构构成,电机工作时在三角机构顶端能形成椭圆轨迹,杠杆机构能调节椭圆轨迹的大小。在电机结构设计过程中利用有限元软件进行关键参数的选择,制造出了样机并进行性能测试。结果表明,电机在低电压、宽频带内能稳定运行。通过改变放大系数,研究了椭圆轨迹对电机输出性能的影响,结果表明,在驱动信号不变时,通过改变放大系数能实现驱动足顶端椭圆轨迹的调节,从而改变电机的输出性能。

    Abstract:

    In order to control the output performance of piezoelectric linear motor by changing the elliptical trajectory of the driving foot, a piezoelectric linear motor based on combined amplification structure was proposed and designed in this paper.The driving foot consisted of a lever and tri angle structure, the elliptical trajectory was formed at the top of the triangle structure when the motor operated,and the lever structure was used to adjust the formed trajectory.Key parameters of the motor were selected according to software emulation in structure design.A prototype was fabricated and tested,and in a wide low frequency range it ran steadly with low driving voltage.The effect of the elliptical trajectory on the motor output performance was studied by changing the amplification factor of the lever structure.It showed that under constant driving signal,the adjustment of the elliptical trajectory at the top of the driving foot was able to realized by changing the amplification factor,thus the output performance of the motor was changed.
