摘要
本文分析了电力机车易于产生动轮空转的主要原因是它对粘着重量利用率比内燃机车有更高的要求。可采用改进机车结构设计及电气补偿两项措施，将电力机车的粘着重量利用率提高到９４～９５％以上。这对重载牵引用电力机车尤为必要。这样，机车的起动牵引力得到充分发挥，还可防止制动时，因车轮滑行而导致的轮轨擦伤故障。
This paper analyses major reasons that electric locomotives are liable to wheelslip. The conclusion is that electric locomotives have higher requirements on utilization factor of adhesive weight than diesel locomotives. The measures of improving locomotive structural design and electric compensation may be taken to raise utilization factor of adhesiveweight of electric locomotives above 94～95%, It is especially necessary for heavy haul electric locomotives. In this way,the starting tractive force of locomotives can be given fullplay, and wheel-rail attrition fault resulted from wheel skidding while in braking can beavoided.
