INTERACTION BETWEEN VEHICLES AND TRACK. LINEAR THEORY VALIDATION EXPERIMENT USING A BOGIE VEHICLE

An experiment is described in which the behaviour of a bogie vehicle with linear suspension parameters is compared with the mathematical model proposed by Committee C 116. Results are presented for two values of primary lateral suspension stiffness. Only the behaviour at the stability margin is compared with theory. Satisfactory agreement is found for the low stiffness case: with the high stiffness value it appears that a true instability was not obtained. This, and the question of subcritical response, require further study. However, useful confirmation of the C 116 mathematical model is demonstrated.
