ABSTRACT: This report presents a methodology based on computer simulation that assesses the safe dynamic performance limits of commuter passenger vehicles. The methodologyt consists of determining the critical design 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 and safety limits and margins are establisheds based on when the predisted behavior approaches a derailment.
