ABSTRACT: This report presents detailed analytic tools and results on dynamic response which are used to develop the safe dynamic performance limits of commuter passenger vehicles. The methodology consists of determining the critical parameters and characteristic properties of both the vehicle and the track, establishing the failure modes, and then using a computer model to determine under what conditions the failure occurs. The computer tool predicts the dynamics of the vehicles at varying speeds. Safety limits and margins are based on when the predicted behavior approaches a derailment.
