Trains running on the track at the prescribed speed are generally safe, but they are evaluated quantitatively by the safety of derailment of the train (lateral force/vertical force, wheel unload ratio). This quantitative evaluation can cause several problems. This is because the derailment safety standard that can express the risk of derailment as an index is not yet established in Korea as a standard or standard. Also, the relation between the change in the radius of curvature and the vehicle derailment is not clearly known. In this study, the influence of deviation on derailment safety is analyzed through numerical analysis to secure the running safety of trains. As a result, the variation rate of the decrease rate of the wheel load ratio is increased sensitively, but the estimated derailment coefficient is almost constant as the passing speed is faster in the wheel load ratio of the outer based on the variation of the curve passing speed. The effect of the change in the ratio of the stopping torque on the outboard wheel to the estimated derailment coefficient at a slightly larger radius of curvature based on the change of the curve radius is small, The value of the estimated derailment coefficient increases sensitively. In addition, the change wheel unload ratio due to the increase of the static wheel load ratio of the outer wheel was sensitively increased at a given radius of curvature. In this way, it can be confirmed that the static wheel load ratio, that is the wheel load deviation, adversely affects the safety of the running of the vehicle.
