This study examines the impact of wheel-rail friction self-excited vibrations and feedback vibrations from corrugated irregularities on rail corrugation, particularly in metro systems. It establishes a finite element model to analyze the dynamic responses of the wheel-rail system on both smooth and worn rail surfaces, revealing that increased friction coefficients and certain corrugation characteristics can exacerbate rail wear. The findings indicate that both self-excited and feedback vibrations play signi
