Abstract:
When the high-speed train brakes, the tread polishers in the braking system will contact the wheel tread and lead to the iron flakes scattering. The data envelopment analysis (DEA) was applied to define several polishers' characteristics and find the most efficient one in the study. Then through the Taguchi experiment method to find the optimized setting to reduce the peeling of iron flakes. The results showed that the peeling rate of the polisher surface dropped from 28% to 2%. It means that the iron fragments scattered on the track have significantly improved, and the risk of short circuits of the track circuit can also be reduced. According to the results of the T-test analysis, there is no significant difference between the optimized design and the original design of wheel tread roughness data.
