Abstract
Whereas air suspension is widely used for railway vehicles as secondary suspension, its hysteretic behavior possibly exerts a non-negligible influence on a vehicle's running characteristics, including unwanted wheel load variations in curves. To enable accurate and quick prediction of vehicle curve negotiation performances considering hysteretic air suspension behavior, this study proposes a new quasi-static curve negotiation analysis procedure using a thermodynamic air suspension system model that expresses in detail nonlinear airflow characteristics. This approach allows the elimination of the limitations of existing full dynamic simulation models associated with high computational intensity and is suited for vehicle running simulations over long-distances.
