牵引计算参数取值对列车牵引质量计算的影响

Compact of Train Traction Indexes on Train Hauled Load Evaluation

论文从列车牵引质量计算和检算要求出发,对DF4b、HXD2b等机车在不同坡道、不同牵引力使用系数时进行计算分析,明确了牵引力使用系数对列车牵引质量计算的影响。同时,根据列车转动惯量系数定义,分析和计算了不同机车和编组构成的列车的转动惯量系数的差异,验证了不同转动惯量系数对列车牵引质量计算结果的影响。通过两个系数的计算分析,给出了改革牵引力使用系数的建议。

According to the requirements of train hauled weight calculation by 《Chinese Train Traction Calculation Standard》 ,this paper calculated train hauled weights of DF4b and HXD2b locomotives with different traction force coefficients. Through calculation and analysis, the influence of the coefficient was made clear. On the other hand, the other train traction index--the moment of inertia coefficient--was analyzed with different locomotives and cars according to its marshalling. The analysis verified the influence of the moment of inertia on the evaluation of train hauled weight. By analyzing the two coefficients, the paper gave a suggestion on the traction force coefficients.
