The invention discloses a railway freight car operation safety assessment method and system. The truck dynamic model is established according to the parameters obtained through research; based on thedata collected by the data acquisition device arranged on a car coupler, the stress condition and the swing angle data of the coupler in actual operation are calculated; the method further comprises the following steps: inputting the calculated data into the constructed dynamic model of the corresponding freight train as external excitation, calculating the dynamic correspondence of each carriage,finally calculating a corresponding safety index according to the dynamic correspondence of each carriage, and respectively judging whether each truck meets a safe operation condition or not. Therefore, the invention can accurately and effectively evaluate whether the multi-section truck marshalling freight train meets the requirements of safety indexes or not under the influence of the swing angle of the coupler, thereby avoiding serious accidents such as derailment and overturning.

    本发明公开了一种铁路货车运行安全评估方法及系统,本发明根据调研所得参数建立货车动力学模型,根据车钩上设置的数据采集装置所采集的数据,计算出实际运行中车钩的受力情况与摆角数据,将其作为外部激励输入至构建好的相应货运列车的动力学模型,计算出每节车厢的动力学相应,最后根据每节车厢动力学相应计算出对应的安全性指标,并分别判断每节货车是否符合安全运行条件。因此,本发明能够准确有效的评估多节货车编组货运列车受车钩摆角影响时是否满足安全指标的要求,从而避免引发脱轨、倾覆等严重事故。
