Abstract :
A linear actuator driven by traveling wave generated by a pair of Langevin vibrators is designed. While one vibrator is assigned as the wave generator and the other one as the absorber, vibrators propel the rail to generate traveling wave so as to drive a guide mounted above. Comprehensive analysis of the Langevin vibrator and the rail is carried out by ANSYS, thus the design is optimized. Practical experiment is completed and the experimental data verify its performance of high speed and large load bearing
