VOLUME III--SUSPENSION DYNAMICS: USE OF AUXILIARY SUSPENSION DEVICES

This report is the final volume of an extensive supsension dynamics parametric study, conducted during Track-Train Dynamics-Phase II. It supplements the two previous reports: R-224 and R-350, published by the Association of American Railroads Technical Center, Chicago, Illinois. The purpose of the study reported in this volume was to evaluate the effects of auxiliary suspension devices on the attenuation of freight car rock and roll motions. Two cars, a 100-ton covered hopper and a 100-ton open-top hopper, were studied in the investigation. The suspension devices studied included constant-contact side bearings; rubber pads, located between the carbody and truck bolsters; and two hydraulic units, A and B, located below the truck bolster in the suspension spring group.
