title = "TO UNDERSTAND THE WHEEL-RAIL FLANGE SQUEAL THROUGH THE CONTACT PERSPECTIVE",
abstract = "This paper presents a study aiming at understanding the mechanism of wheel-rail flange squeal through the contact perspective. The study systematically demonstrates the connection between the observed wheel-rail flange squeal noise and contact force by measurements and numerical simulations. An integrated transient model enhanced by genuine 3D surface irregularities is developed. Features of flange squeal under four-speed levels corresponding to in-situ experiments are reappeared incorporating both global dynamics and local contact status. Generation mechanism of flange squeal is proposed by measurement observation and confirmed through the proposed model with multiple influencing key factors.",
