摘要：A design of cylindrical type piezoelectric mobile actuator is proposed and analyzed in the paper. Traveling wave is generated on the top area of the actuator applying harmonic oscillations with different phases. Electrodes of piezoceramic elements are excited by harmonic voltage with phase difference of 2π / 3. Numerical modeling based on finite element method was performed to find resonant frequencies and modal shapes of the actuator and to calculate the trajectories of the upper points movements under excitation scheme. Path-Planning algorithm presented for cylindrical piezoelectric mobile actuator.
