Roll dynamics of 100 ton N.Y.C. Hopper car on staggered joint track (TN-DYN-066)

The equations of motion for the hopper car body in pitch, roll and bounce are written down and programmed for the PACE Analogue Computer. The programs were used to study the care response to staggered joint track. The violent rolling at speeds around 18 m.p.h. observed in the actual vehicles...
