由寅茨提出的整个车列的单位(就车列的重量而言)运行阻力的一个公式,它的准确性通过严密的试验而被证实: 其中,m_A是每个车轴上的车辆重量(轴重),它可以从下式得出: 这里m_W和n_A是整个车列的重量和轴数(轮对)。公式(1)中用m_A来考虑机车车辆运行阻力同装载状况的关系。参数α、K、χ和μ的值分别按机车系列列在表中(文献〔1〕P371～372)。表中数字随重量比例的变化而变化: 列车的总重量为: 式中m_T为机车的整备重量。以上列举的参数与γ_％的关系可用曲线表示。例如:图1为120型机车的曲线,令人注
The formula for running resistance of a unit of the entire train (in terms of the weight of the train) proposed by Inje, whose accuracy is confirmed by rigorous testing: where m_A is the weight of the vehicle on each axle Weight) which can be derived from: where m_W and n_A are the weight and number of axes (wheel pairs) of the entire train. In equation (1), m_A is used to consider the relationship between the running resistance of rolling stock and the loading condition. The values of the parameters α, K, χ and μ are listed in the table for the locomotive series (Reference [1] P371-372). The figures in the table vary with the weight ratio: The total weight of the train is: where m_T is the curb weight of the locomotive. The above listed parameters and γ_% of the relationship between the curve can be expressed. For example: Figure 1 for the 120 locomotive curve, it is noteworthy
