摘要
建立了简单车辆编组动力学模型,计算了车辆曲线通过时制动对车辆安全性的影响,评价了车辆曲线段内的脱轨安全性。发现曲线通过时制动对动车组车辆脱轨安全性影响较小,但可能出现制动力超过轮轨切向力而打滑现象。
The simple dynamic model for vehicle marshalling is established, the influence on the safety of curve pass under emergency brake case is analyzed by calculating, and the train derailment safety of the curve segment is evaluated. It is found that the braking has less effect on EMU derailment safety when the train passes curve, but the skid phenomenon may occur due to braking force exceeds wheel / rail tangential force.
