Complex Eigenvalue Analysis of Railway Wheel/Rail Squeal: Advanced Study

Wheel/rail squeal noise of trains is one of the challenging problems to be solved. Several models such as self-excited instable vibration due to negative damping, flutter instability, hammering effect due to local defects, etc. were proposed, but a successful model for the squeal problem has not been presented until now. In this study, experimental and…
