摘要
针对青藏线格—拉段所处地区恶劣的自然条件 ,独特的线路特征和特殊的运营组织要求 ,提出了对青藏线高原内燃机车的选型原则。根据此选型原则和国内外内燃机车现状 ,就高原内燃机车主传动方式的选择、功率等级的确定、牵引模式的考虑等问题进行了分析研究。提出了青藏铁路高原内燃机车宜采用交—直流传动 ,以及机车功率定为 2 5 0 0kW～ 2 70 0kW ,采用两台固定编组的单司机室机车等观点。同时还分析了为了适应青藏线恶劣的自然条件 ,必须进行研究的课题。另外 ,认为以目前国内批量生产的功率最大的东风 11、东风 8B机车作为开发平台 ,研制高原客、货运内燃机车 。
Based on the unique characteristics of Qinghai Tibet Plateau Railway (Section of Golmud to Lhasa), customers′ requirements, and the current status of locomotive research and manufacturing in China, several principles have been proposed of choosing the locomotive to be used on Qinghai Tibet Plateau Railway pertaining main transmission mode, power grade and tractive mode of locomotive. A list of topics that research must address so that the new locomotive can keep good working condition under the harsh natural environment on Qinghai Tibet Plateau are also propounded. Finally, it is proposed to develop the locomotive based on the DF11 and DF8B diesel locomotives, which are mass produced and have the largest power at home.
