COMPARISON OF THE NONLINEAR DYNAMIC CHARACTERISTICS OF BARBER S-2 AND ASF RIDE CONTROL FREIGHT TRUCKS

The results of an experimental and analytical program to define the load deflection characteristics of a Barber S-2 freight truck and to compare these characteristics to those of an ASF freight truck of the same load capacity are presented. The comparison of the two trucks is made on a parameter basis and on the basis of the wheel/rail loads induced by track misalignment. The results indicate there is very little difference in the parameters and the response of the two trucks. This is of course qualified by the assumptions required in the development of the mathematical models.
