This paper presents a new proof-of-concept design of inchworm-type piezoelectric actuator for precision positioner which avoids the tight tolerance and could be easily assembled. The proposed design uses two parallel linear guiding rods as a guide different from the previous configurations which adopted a guide channel or a moving shaft and the clamping clearance is adjustable. For the optimum design...
This paper presents a novel proof-of-concept design of an inchworm-type piezoelectric actuator. The proposed design uses two parallel linear guiding rods with ball bearings as a guide different from the previous configurations which adopt a guide channel or a moving shaft. Finite element analysis has been used to achieve the optimal design parameters with the frame stiffness, the dynamic performance...
