• Description:
  The mathematical model of a sprung mass moving along a simply supported beam is used to analyze the dynamics of a power-collection system. A computer simulation of one-dimensional motion is used to demonstrate the phenomenon of collector-power rail interaction. Parametric resonance in an undamped collector is shown to exist at several speeds below 300 miles per hour. However, it is demonstrated that amplitude can be controlled at all of these resonant speeds with the proper use of damping. (Author)
