评估列车能量消耗对促进铁道车辆节能十分重要。列车能量消耗可由全面的测量或数值仿真进行评估,但这些方法需要耗费大量的时间和精力。因此,我们开发出一种不用数值仿真评估能量消耗的简易计算方法。将测量结果与计算结果进行比较后表明,这种计算方法误差低于9%。 It is very important to evaluate the train energy consumption to promote the energy saving of railway vehicles. Train energy consumption can be assessed by comprehensive measurements or numerical simulations, but these methods require considerable time and effort. Therefore, we developed a simple method of calculating energy consumption without numerical simulation. Comparing the measurement results with the calculation results shows that the error of this calculation method is less than 9%.
