| Abstract: | In order to develop a kind of great step-space and high precision actuate-motion mechanism,a new type of actuate-motion mechanism constructed with giant magnetostrictive material and piezoelectric stack has been investigated,which are similar each other in drive principle and usage.Based on the moving process,the principle and control mode of the mechanism are introduced.Results of the experiment show that,the actuate-motion mechanism can move forward and backward along the rail under the control of the given signal,the maximum displacement of single forward step can be up to 20 μm.The actuate position requirement can be throughment controlling the step displacement with the adjustment of driving voltage. |
