以神华铁路运输专线上运行的万吨重载列车为研究对象,通过试验测试,获得机车运用条件下列车制动系统的制动波速、列车管减压、制动缸升压等制动系统特性。结果表明,HXD1型机车2+1+0编组时,中间机车滞后时间平均为1~2 s;HXD1型机车编组列车制动波速为232m/s;列车管减压50 k Pa时,列车制动缸的平衡压力均在120 k Pa左右。
Taking the 10,000-ton heavy-haul train running on the Shenhua-Huzhou railway line as the research object, the braking system characteristics such as the braking wave speed, the train-tube decompression and the brake cylinder boosting under the condition of locomotive operation are obtained through the test. . The results show that when the HXD1 locomotive is 2 + 1 + 0, the lag time of the middle locomotive is 1-2 seconds on average; the braking speed of the train of the HXD1 locomotive is 232m / s; when the train tube depressurizes 50 kPa, the train braking The cylinder’s equilibrium pressure is around 120 kPa.
