Abstract

The main technical parameters of the locomotive for quarry railway transport have been evaluated. The design parameters of the locomotive have been determined and it is established that the tangential power is 6700 kW, and the traction force for the design mode is 1300 kN. The calculations of the traction characteristics of the locomotive have been performed. The procedure for determining the parameters of the locomotive operating modes during train tasks performing has been proposed, which is based on the processing of the results of traction task solving on the section of the track. It has been established that for the test section of the track a significant part of the time in the traction mode the locomotive operates with a load of 10… 25% of the nominal, therefore it has been proposed to implement the mode of movement with disconnection of traction motors. The use of an onboard energy storage system, which allows the accumulation of energy during electrodynamics braking has been proposed. The generalized scheme of traction system which allows realizing ways of increase of energy efficiency a rolling stock has been offered.

铁路职业运输机车技术参数评定

对采石场铁路运输机车的主要技术参数进行了评价。确定了机车的设计参数，确定了机车的切向功率为6700 kW，设计模式的牵引力为1300 kN。对机车的牵引特性进行了计算。提出了在轨道段牵引任务求解结果处理的基础上，确定列车任务执行过程中机车运行模式参数的方法。在轨道试验段，机车在牵引模式下有相当一部分时间的负荷为标称负荷的10 ~ 25%，因此提出了采用不连接牵引电动机的运行模式。提出了一种车载能量存储系统的使用，该系统允许在电动力制动期间积累能量。提出了牵引系统的通用方案，为提高车辆的能效提供了实现途径。
