摘　　要：针对我国牵引18～20节客车、速度200km／h的运营条件，确定6、8轴机车所需功率。从列车的剩余加速度、启坡能力、加速时间和距离方面对6、8轴机车牵引能力进行计算分析比较。6轴和8轴机车均能满足我国200km／h提速的需要，其牵引性能相当。在节能、机车制造、购置、运营和维护等方面，6轴机车优于8轴机车。Based on application condition of drawing 18 to 20 passenger cars in our country, the power of 6 - axle and 8 - axle locomotive is determined. The traction capacity between 6- axle and 8 - axle locomotive is calculated and compared with respect to train remainder acceleration, start slope capacity, speedup time and speedup distance. Whatever 6 - axle or 8 - axle locomotive, the traction power can meet the traction demand for 200 km/h passenger car, and the traction performance is similar. The 6- axle locomotive in some respect, such as energy - saving, locomotive manufacture, purchase, application and maintenance, is better than 8 - axle locomotive.
