摘要
阐述了轮径差对列车牵引系统的影响,验证了增加轮径校正功能可以消除轮径差对列车防滑功能和恒速功能的影响。以时速350km中国标准动车组用YJ268A型牵引电机为例,详细计算了轮径差与牵引电机负荷不平衡的数值关系,并给出了轮径差超限后的保护措施。
The effect of wheel diameter difference on traction system of the train is expounded,and adding the wheel diameter correcting function can eliminate the effect of wheel diameter difference on the anti-slip function and constant speed function of the train is verified.With the YJ268 Atraction motor for350 km/h standard Chinese multiple units as the example,the digital relation between the wheel diameter difference and the unbalanced load on the traction motor is calculated in detail,and the protective measures after the wheel diameter difference exceeding the limit are given out.
