设计矿用电机车时,其牵引电动机的单位“小时功率”应该等于:N_(уд)=N_(час)/P=(1000ψ+ω_0′)v_(час)/102η_p千瓦/吨(1)其中,N_(час)——电机车的小时功率,千瓦;P——电机车的粘着重量,吨;ψ——电机车的设计粘着系数,ψ值可依照电机车的实际设计使用条件决定;ω_0′——电机车空载运行时的此阻,公斤/吨;V_(час)——电机车的小时速度,米/秒;η_p——减速器效率。根据德聶伯彼得洛夫斯克矿业学院对顿巴斯绝大多数煤矿的轨道表面状况的实验资
When designing a mining electric locomotive, the unit “hour power” of the traction motor should be equal to: N_ (уд) = N_ (час) / P = (1000ψ + ω_0 ’) v_ (час) / 102η_p kW / ) Where, N_ (час) - hour power of electric locomotive, kilowatts; P - adhesive weight of locomotive, ton; ψ - designed adhesion coefficient of locomotive, ψ value can be determined according to the actual design and application conditions of electric locomotive ; ω_0 ’- the resistance of the electric locomotive in no-load operation, kg / ton; V_ (час) - hour speed of the electric locomotive, m / s; η_p-- reducer efficiency.
