The invention discloses a multi-train linkage heavy haul railway train hook jumping separation prediction method, belongs to the field of railway train longitudinal dynamics application, solves the problem of heavy haul railway train hook jumping prediction, and is characterized in that a certain number of locomotives are taken forwards and backwards by taking concerned coupler pairs as centers; according to online running dynamics analysis of the whole train, running parameters and borne external force of each train are obtained; calculating the track vertical bearing force increment of the bogie of the locomotive, obtaining the nodding angle and the front and rear coupler heights, and obtaining the coupler height difference of the coupler pair and the height of the coupler force acting point; the draw gear force acting point deviates from the draw gear center line, and the draw gear force generates vertical component force; comparing the vertical component force of the coupler force with the friction critical value provided by the coupler pair, and judging whether the coupler pair has the hook jumping risk or not; acquiring a hook height difference allowable value according to the critical value of the vertical deflection angle under the action of the coupler force; according to the method, heavy-load train hook jumping separation prediction can be realized.

    一种多车联动的重载铁路列车跳钩分离预测方法,属于铁路列车纵向动力学应用领域,解决重载铁路列车跳钩预测的问题,要点是以被关注的车钩对为中心向前和向后各取一定数目的机车车辆;根据整个列车在线运行动力学分析,获取相关每节车的运行参数和承受的外力;计算机车车辆转向架的轨道垂向支承力增量,获取其点头角及前后车钩高度,获取车钩对的钩高差及车钩力作用点的高度;所述车钩力作用点偏离车钩中心线,车钩力产生垂向分力;根据车钩力的垂向分力与车钩对所能提供的摩擦力临界值比较,判断车钩对存在或不存在跳钩风险;根据所述车钩力作用垂向偏角的临界值,获取钩高差允许值;该方法能够实现重载列车跳钩分离预测。
