摘要
阐述了圆盘型压电振子驱动器的工作原理,并对驱动器的结构进行设计.对驱动器进行有限元建模,再进行模态分析,求出系统的固有频率为225.12 Hz.再对其进行频响应分析,分别绘制出位移和电压、位移和频率之间的关系曲线图.研究表明,系统的位移输出量和激振电压、频率有关,在固有频率状态下,位移输出量达到最大.
The working principle of disc type piezoelectric vibrator drive was expounded in this paper,and the structure of the drive was designed. The drive was made to finite element modeling. Then the modal analysis was performed,and the natural frequency of the system was 225. 12 Hz. After the frequency response analysis,the figure of displacement and voltage and the displacement and frequency curve were mapped respectively. The results showed that the displacement of the system output was related to the excitation voltage and frequency,and in the condition of natural frequency,displacement output reached the maximum.
