摘要
基于压电双晶片提出一种新型准静态直线压电驱动器,可通过阵列的方式获得所需机械输出力,结构简单,性能稳定,可控性强。利用有限元软件对驱动器结构进行设计与分析,并加工制造了该驱动器的物理样机。最后通过实验发现,当驱动频率为500~2 100Hz时,驱动器可直接输出直线运动。当驱动频率为1 100Hz,驱动电压峰-峰值为200V,预紧力为1.5N时,该驱动器最大输出速度可达95mm/s,最大输出力为0.7N。
A novel quasi-static linear piezoelectric actuator based on the piezoelectric bimorph was presented.The proposed actuator can output desired mechanical output force by means of multiple bimorphs array and has the advantages of simple structure,stable performance and strong controllability.The actuator structure was designed and analyzed by using the finite element software,and the physical prototype was manufactured.The experimental results show that the actuator can output the linear motion directly when the driving frequency is between 500 Hz and 2 100 Hz.The maximum no-load speed of the actuator is 95 mm/s,and the maximum output force is 0.7 N with the driving voltage peak-peak value of 200 V at the driving frequency of 1 100 Hz,and preload of 1.5 N,respectively.
