1）弓网接触力  Contact Force of Pantograph Network

a）上行方向运行  Running in up-going direction

前弓弓网接触力在180km/h～275km/h的试验速度下，平均接触力分布在50N－80N范围内，接触力最大值分布在70～130N，最小值分布在20～50N。

While the front pantograph network contact force is within the testing speed from 180km/h to 275km/h, the average contact force is distributed within the scope from 50N to 80N, the maximum value of contact force is distributed within the scope from 70 to 130N, and the minimum value is distributed within the scope from 20 to 50N.

后弓弓网接触力在180km/h～275km/h的试验速度下，平均接触力分布在60N－80N范围内，接触力最大值分布在90～120N，最小值分布在20～60N。

While the rear pantograph network contact force is within the testing speed from 180km/h to 275km/h, the average contact force is distributed within the scope from 60N to 80N, the maximum value of contact force is distributed within the scope from 90 to 120N, and the minimum value is distributed within the scope from 20 to 60N.

b）下行方向运行

Running in down-going direction

前弓弓网接触力在180km/h～275km/h的试验速度下，平均接触力分布在80N－120N范围内，接触力最大值分布在110～160N，最小值分布在50～90N。

While the front pantograph network contact force is within the testing speed from 180km/h to 275km/h, the average contact force is distributed within the scope from 80N to 120N, the maximum value of contact force is distributed within the scope from 110 to 160N, and the minimum value is distributed within the scope from 50 to 90N.

后弓弓网接触力在180km/h～275km/h的试验速度下，平均接触力分布在50N－80N范围内，接触力最大值分布在80～140N，最小值分布在10～50N。

While the rear pantograph network contact force is within the testing speed from 180km/h to 275km/h, the average contact force is distributed within the scope from 50N to 80N, the maximum value of contact force is distributed within the scope from 80 to 140N, and the minimum value is distributed within the scope from 10 to 50N.

比较受电弓上行和下行两个运行方向前弓和后弓弓网动态接触力测试数据，可以看出，后弓弓网接触力变化范围较前弓大，说明后弓受电弓的运行平稳性较前弓差；弓网接触力最大值、平均值和最小值随速度的变化曲线符合试验大纲规定。

By comparing the testing data of front pantograph and rear pantograph networks under the up-going direction and down-going direction of pantograph, we can see that the variation scope of rear pantograph network contact force is larger than that of front pantograph network. This indicates that the running stationarity of rear pantograph is poor than that of front pantograph. The variation curves of the maximum value, average value and minimum value of pantograph network contact forces comply with the regulations of the test outline.

2）接触网高差  Height difference of contact network

接触网高差较小，大部分分布在100mm以下。上行和下行方向受电弓后弓运行时有个别点高差大于试验大纲规定的150mm，且后弓受电弓高差比前弓高差大，说明受电弓处于后弓位置时所受到的震动幅度较大。

The height difference of contact network is small, and most of them are less than 100mm.  During the running of rear pantograph in up-going and down-going directions, the height difference of individual points is larger than 150mm as specified by the test outline, and the height difference of rear pantograph is larger than that of front pantograph. This indicates that the shaking amplitude while the pantograph is at rear position is larger than that at front position.

3）硬点  Hard point

硬点大部分数值分布在10g～60g，仅有个别点硬点测量值超过60g。硬点数值分布符合试验大纲规定。

Most values of the hard points are distributed within the scope from 10g to 60g, and only the measuring values of some hard points exceed 60g.  The distribution of hard point values comply with the regulations in the test outline.

4）离线（火花）Offline (sparkle)

上行和下行两个运行方向后弓弓网离线火花次数均较前弓多，但无大的拉弧现象发生，离线次数符合试验大纲规定。

The offline sparkle times of rear pantograph is more than that of front pantograph while running is both up-going direction and down-going direction. However, there are no large arcing problems. The offline times comply with the regulations in the test outline.

CRH1型长编组卧铺动车组在京哈线秦沈区段250km/h速度级及以下的弓网受流性能满足试验大纲要求。

The current receiving performance of pantograph network while the CRH1 marshalling sleeper MU is running with the speed level of 250km/h or less on the Qinhuangdao-Shenyang Section of Beijing-Harbin Railway complies with the requirements of the test outline.
