TRUCK AND CARBODY CHARACTERIZATION

Martin Marietta Corp. has developed a mathematical model of an 80-ton hopper car and its Ride Control Trucks to be used to provide response information about curving, hunting and track irregularities. This report summarizes laboratory tests, analytical model derivation and comparative stability analyses. One objective was to develop a test/analysis philosophy to permit evaluation of the dynamic behavior of other truck/car configurations.
