Fig. 12. The evolution of wheel polygonal wear simulated with flexible wheelset at 50 km/h (a, b), 60 km/h (c, d), and 70 km/h (e, f), and the P2 resonance frequency is 75–85 Hz. The left figures (a, c, and e) are the development of radius deviation, and the right figures (b, d, and f) are the growth of roughness levels described in order.
