ANALYSIS OF THE DYNAMICS OF A RAIL CAR FROM ITS RESPONSE TO RANDOM INPUT

The parameters which define the dynamic behavior of a physical system can be determined by analyzing the response of the system to a random input. Application of the random process technique to one of the U.S. Department of Transportation's rail research cars is described. One of these railcars was instrumented, operated over selected portions of mainline track between Washington and Baltimore, and analyzed for its dynamic properties. The theory and experiment are described, and the dynamic model of the railcar which was used is briefly presented. Results including natural frequencies for the car system, mode shapes for the principle modes, and revised values for important parameters are presented.
