Abstract
A type of drive foot with displacement amplification was proposed based on analysis of the friction drive principle of the non-resonant linear piezoelectric motors. Firstly, the displacement amplification mechanism of the drive foot was carried on and the elliptical trajectory equation of the drive tip was deduced through the mechanism model of the drive foot. The optimization design of main structure parameters was conducted with finite element analysis software to analyze the influences of displacement amplification. The simulation results showed that the maximum magnification factor can be obtained when H(the thickness of flexible arm) is 0.8mm and θ (the flexible angle) is 12°. A linear piezoelectric motor prototype was designed and fabricated, the experimental results indicated that this kind of motor can run steadily in a wide range (the operation bandwidth is beyond 1kHz) and that the thrust can be 0.35N and the maximum velocity can be 2.5mm/s when the operation frequency is 4kHz and the operation voltage is 90V.
