SIMULATION OF LATERAL DYNAMICS FOR A CONTACT POWER COLLECTION SYSTEM

The mathematical model of a sprung mass moving along a simply supported beam is used to analyze the lateral dynamics of a power collection device as it slides along a power rail. A computer simulation of one-dimensional motion is used to demonstrate the phenomena of collector-power rail interaction. Parametric resonance in an undamped collector is shown to exist at several speeds below 300 mph. However, it is demonstrated that amplitude can be controlled at all of these resonant speeds with the proper use of damping.
