Abstract
By using the finite element analysis software
a nano-stepper piezoelectric micro-positioner with long-range is established and simulated.Influence of structural parameters on the stepper piezoelectric micro-positioner is investigated and its natural frequencies and mode shapes are analyzed.The orthogonal experiment methods are used to arrange the test structure design parameters and optimizing design parameters of the configuration of the device are gained.A mathematical model using stepwise regression is built to quantitatively analyze the influence of parameters of stepper piezoelectric micro-positioner.
