A Piezoelectric In-Pipe Micro Robot with Impact-Drive Actuation

摘要：

A piezoelectric in-pipe micro robot with bimoph structure and and actuated by the Impact Drive Mechanism(IDM) theory is presented in this paper.Two piezoelectric bimorph and an inertia mass connected in series compose the basic structure of this actuato.While operating,the deflection of the two piezoelectric bimorph sheets is translated into linear movement by the IDM,thus completing the actuation of the system.As the essence of the IDM theory,the relationship between the inertia impact force generated by the deflection of the bimoph sheets and the friction between the moving body and the inwall of the pipe is analyzed theoretically.And then the dynamic performance of the system is simulated both by MATLAB and ANSYS.The results verified proves that the proposed actuator is an accurate and efficient solution for medical and industrial applications.
