摘要
本文利用气体动力学原理建立的列车空气制动系统模型，预测了在“过管”条件下主补机不同匹配位置和不同动作时间差时，组合列车常用制动特性。预测结果表明：主补机同步制动时，补机的最佳位置应位于列车的约３／４处；调整补机位置和主补机动作时间差都可以改善列车制动同步性，但通过改变补机位置调整列车制动同步性效果更加理想。本工作的开展对组合列车的运输组织及操纵具有指导意义。
緽ase on gas dynamics，a mathematical model of air brake system including GK triple valves and JZ7 locomotive valves has been established．The prediction of service application oerformances of connected trains has been done with this model，in which the second locates at differenct positions and acts ahed the first locomctive at different times．The predictions show that the best position of the second locomotive is at 3／4 of the train and that it is better to adjust the position of the second locomotive than to adjust the time spacing of the first and second locomotive for braking coincidence of the train．This rasearch is significance for the connected train transportation．【
