摘要：
A novel anti-slip control strategy considering electromagnetic effort is proposed to enhance the adhesion level and prevent slipping problems of metro wheels under low-adhesion friction conditions. To this end, a metro train-slab track coupled dynamics model is established, in which the non-linear wheel/rail interactions and the advanced anti-slip control module are treated. The wheel/rail interactions and anti-slip controlling effect under complex wheel/rail friction conditions and traction/braking operations are numerically investigated. The simulation results indicate that the powered wheelset is prone to slip under low-adhesion conditions. The proposed anti-slip controller can improve wheel/rail adhesion level and restrain wheelset slipping phenomenons with the increasing wheel/rail vertical forces. Moreover, the employed anti-slip controller improves traction/braking efficiency compared to the traditional one. © 2024 Chinese Mechanical Engineering Society. All rights reserved.
