摘要
基于列车空气制动特性多参数数学简化方法,研究了制动控制阀特性参数、制动缸充气特性参数、制动波传播速度特性参数等对列车制动缸充气特性曲线的影响。对150辆装用120型空气制动阀的重载列车制动系统进行了计算,并与试验结果进行了对比,结果表明该方法快捷有效。
On the basis of the multi-parameter mathematic simplification method for air braking features of trains,the effects of such parameters as braking control valve features,brake cylinder charging features and braking wave propagation speed features on the curve of brake cylinder charging features of trains are researched,calculation is made for the braking system for the heavy haul train of 150 cars mounted with 120 air brake valves and compared with the test result.The result shows that the method is rapid and efficient.
