Abstract

This paper deals with the influence of mechanical resonance on the dynamic performance of a tubular linear actuator with Halbach array. Control parameters are obtained from both measurements and analytical solutions. And then, the voltage and the motion equation of the tubular linear actuator are established. In particular, by expressing mechanical components as the motional impedance, this paper investigates the variation of power dissipated in the linear actuator with spring vs. frequency. Finally, the simulations and experiments for dynamic characteristics of the moving-magnet linear actuator with spring are presented for various values of frequency.
