为了满足繁忙干线重载化与电气化,在电气与内燃牵引动力加速代替蒸汽牵引动力的形势下,我国重型货运机车东风,型机车将承担更繁重的任务。由于东风,型机车与电力机车(韶山_1、韶山_4)相比,在功率、粘着牵引力及轴式等级三方面都略有逊色,因此合理地选择干线机车基本参数是一项重要的决策性问题。参照电力机车型谱研究,确定内燃机车选型原则为:(1)兼顾客货运输的需要,柴油机机型与牵引电动机类型尽可能少;(2)一般用单机牵引,必要时用双机牵引,避免出现三机牵引;(3)适当的功率储备和稳妥的粘
In order to meet the heavy load and electrification of busy trunk lines, under the circumstance that electric power and internal combustion traction power accelerating instead of steam traction power, the heavy-duty locomotive Dongfeng and locomotives in China will undertake more heavy tasks. As Dongfeng locomotives are somewhat inferior in power, adhesive traction and axle grade compared with electric locomotives (Shaoshan_1, Shaoshan_4), it is an important decision to select the basic parameters of the main line locomotive reasonably Sexual issues. With reference to the study of electric locomotive spectrum, the principle of selection of diesel locomotives is determined as follows: (1) taking into account the needs of passenger and freight transport, the diesel engine type and the traction motor type are as few as possible; (2) generally using single traction and dual traction if necessary , To avoid three machine traction; (3) appropriate power reserve and secure sticky
