Experimental and Numerical Investigation into Formation of Metro Wheel Polygonalization

<div>Measured vertical acceleration of the axlebox right after wheel reprofiling: (a) time-domain signal for a vehicle running on different types of track (T-1 for monolithic concrete bed with DTVI2 fasteners, T-2 for monolithic concrete bed with compression-type fasteners, T-3 for low-weight floating slab track, and T-4 for high-weight floating slab track); (b) time-frequency spectra of acceleration.</div>
