摘要

摘要: 研究了时速250 km以上高速列车制动系统, 分析了高速列车的运行阻力、制动力与制动距离。根据目标距离模式曲线理论, 建立了高速列车的制动模式曲线分段迭代模型。应用MAT-LAB/Simulink软件, 分析了CRH2-300型高速列车在平直道上、15‰与25‰直坡道上的运行阻力的变化, 对比了CRH2-300型和CRH3型高速列车在制动初速为300 km.h^-1时的常用和紧急制动曲线。计算结果表明: 在平直道上, CRH2-300型高速列车紧急制动距离为2 786.68 m, CRH3型高速列车紧急制动距离为3 319.37 m, 均满足紧急制动距离小于3 700 m的制动要求; 仿真制动曲线和实际制动曲线基本一致, 验证了分段迭代算法的有效性。

Abstract: The braking system of high-speed train above 250 km·h^-1 was studied, and the running resistance, braking force and braking distance of high-speed train were analyzed. Based on curve theory of target distance mode, the piecewise iteration model of braking mode curve for high-speed train was proposed. With MATLAB/Simulink software, the changes of running resistances on flat-straight line, direct ramp with grade 15‰ and direct ramp with grade 25‰ for CRH2-300 type high-speed train were analyzed, and the normal braking curves and emergency braking curves of CRH2-300 type and CRH3 type high-speed trains at initial braking speed 300 km·h^-1 were compared. Calculation result indicates that the emergency braking distance of CRH2-300 type high-speed train is 2 786. 68 m on direct ramp, the emergency braking distance of CRH3 type high-speed train is 3 319. 37 m on direct ramp, and both of them are less than 3 700 m, which is the maximum braking distance of braking requirement. Simulation braking curves almost consistent with actual braking curves, which verifies the validity of piecewise iteration algorithm.
