Effect of Wheel Diameter Difference on Traction System of the Train and Corresponding Protection Measures
LIANG Dawei;Technical Center of CRRC Qingdao Sifang Rolling Stock Research Institute Co.,Ltd.;
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.
