This paper presents a novel driving principle by means of the parasitic motion of the microgripper. Actuators based on this principle can realize the large displacement range and high speed easily. Also the structure can be simple. A parasitic motion principle linear actuator mainly consisting of two piezoelectric stacks, two microgrippers and a mover was designed. Experimental results indicate that at a low driving frequency of 5 Hz, large velocity over 40 μm/s is obtained with the driving voltage of 100 V. Backward motion was observed and analyzed. Experimental results verify the feasibility of the new principle and it can be used to design new linear or rotary actuators.
本文提出了一种基于微夹钳寄生运动的新型驱动原理。基于该原理的致动器能够轻松实现大位移范围和高速度。而且其结构可以很简单。设计了一种主要由两个压电叠堆、两个微夹钳和一个动子组成的寄生运动原理线性致动器。实验结果表明，在5Hz的低驱动频率下，施加100V的驱动电压可获得超过40μm/s的大速度。观察并分析了反向运动。实验结果验证了该新原理的可行性，并且它可用于设计新型线性或旋转致动器。
