Abstract

A new stick-slip type piezoelectric actuator based on asymmetric structure is proposed. The actuator uses a stator with the asymmetric diamond-shaped structure, and the structure size is determined by finite element simulation. First, the structure and working principle of the proposed actuator are introduced. The elongation deformation of the piezo stack is transferred to the driving tip by the used asymmetric diamond-shaped hinge. This produces a diagonal movement on the driving tip, with the lateral motion used for driving and the longitudinal motion used for pressing the slider, respectively. Then, the statics analysis of the proposed piezoelectric actuator is performed by finite element simulation. The simulated displacements of the driving tip under different structures are obtained, and then the structure size is determined. Finally, an experimental system is established to study the performance of the proposed piezoelectric actuator. The experimental results show that the maximum output velocity of the proposed actuator is 5.26 mm/s. The maximum output force is 1.9N when the locking force is 2N and the drive frequency is 660 Hz.

基于非对称菱形挠性铰链结构的新型粘滑式压电致动器

本文提出了一种基于非对称结构的新型粘滑式压电致动器。该致动器采用非对称菱形结构的定子，并通过有限元仿真确定了结构尺寸。首先，介绍了所提出的致动器的结构和工作原理。压电叠片的伸长变形通过所使用的非对称菱形铰链传递到驱动尖端。这就在驱动顶端产生了对角运动，横向运动用于驱动，纵向运动用于按压滑块。然后，通过有限元模拟对所提出的压电致动器进行静态分析。得到不同结构下驱动尖端的模拟位移，然后确定结构尺寸。最后，建立了一个实验系统来研究拟议压电致动器的性能。实验结果表明，所提出的致动器的最大输出速度为 5.26 mm/s。当锁定力为 2N 和驱动频率为 660 Hz 时，最大输出力为 1.9N。
