计算表明,ND_5型机车前后转向架采用不对称布置的目的在于提高机车正向牵引时的粘着重量利用率,但却使3、6两轴在牵引力作用下严重过载,最高时达295kN,应当引起足够重视。转向架的不对称布置也使机车反向牵引时粘着重量利用率下降。研究表明,在粘着重量利用率和起动性能方面,在轴重的过载方面,国产东风_4和东风_8型机车均优于ND_5型机车。
The calculation shows that the asymmetrical arrangement of the front and rear bogies of ND5 locomotives is to improve the utilization of the weight of the locomotive when it is towed forward, but it causes serious overload of the 3 and 6 axes under the traction force, up to 295kN, which should cause Pay enough attention. The asymmetrical arrangement of the bogies also reduces the adhesion weight utilization when locomotives pull in reverse. The research shows that the domestic Dongfeng_4 and Dongfeng_8 locomotives are better than the ND_5 locomotives in terms of the weight-bearing utilization and start-up performance in axle load overload.
