Wheel wear reduction of a mechatronic two-axle vehicle controlled with feedforward wheelset steering approaches

The mechatronic vehicle developed within the Shift2Rail projects Run2Rail, Pivot, NEXTGEAR, and Pivot2 is evaluated with respect to wheel wear. KTH wear model used determine coefficients of Archard’s map reproduce measured worn profiles present running on Metro Madrid line 10. same then evaluate performance controlled two variants a feedforward controller. first one uses on-board measurements, while second optimised using firefly optimisation algorithms assuming knowledge travelled track. control strategy based measurements shows improvements above 60% in terms lost volume due wear, compared standard bogie vehicle. controller reaches 70%. Good coherence found between predicted number ones achieved volume.
