HARMONIC ROLL SERIES. VOLUME 4: TORSIONAL AND FLEXURAL CAR STIFFNESS CHARACTERISTICS

This phase of the Track Train Dynamics Program determined experimentally the torsional and flexural rigidity of three box cars, one covered hopper car and one flat car. Shorter cars displayed a larger value of torsional rigidity than the longer ones. The piggyback flat car was the least rigid. The unibody construction of the covered hopper proved to be the stiffest of cars tested. Recommendations are made about instrumentation for future cars to be tested.
