Paper Abstract

We study the dynamics of servomechanisms in which power is transmitted from the motor to payload using a flat steel belt. The bandwidth of control in such systems is usually limited by a resonance in which the payload and motor oscillate out of phase and the belt undergoes longitudinal strains. In this paper, we conduct experiments on a linear positioning system, show that significant damping in the drive resonance can be attained by attaching a layer of low-wave-speed foam to the belt, and develop a simple model of this damping phenomenon.
