Short summary
This paper analyses the effects of several typical polygon amplitudes and orders on wheel sound radiation in metro lines. Concurrently, research has found that there is no linear relationship between wheel–rail forces and polygon amplitudes. Furthermore, the noise reduction mechanism of resilient wheels is thoroughly explained in terms of damping, energy dissipation, vibration isolation, decoupling, and acoustic impedance characteristics.
