关于适宜青藏铁路运行的七轴内燃机车的设想

Conception of the 7-axles diesel locomotive suitable for Qinghai-Tibet Railway

青藏线的运用及维护保养关键之一在于怎样解决机车与线路的轮轨动力学问题。提出一种新的机车方案,从各个方面解决轴重、粘重、簧下质量以及机车速度等方面的问题,将轮轨作用力对线路的破坏量减到最小,从而达到易于长期维护保养青藏线路的目的。

Treatment of wheel-rail interation is of importance for operation and maintenance of locomotive running in Qinghai-Tibet Railway. In this paper,a locomotive scheme has been put forward, which, in diffrent aspects, will solve several problems such as axle load, adhesion load, unsprung mass and locomotive speed, etc. The new scheme will minimize the destructive effect on track by wheel-rail force, so that the Qinghai-Tibet railway can be kept in good condition for a long period of time.
