Abstract

This paper presents experimental analysis of a friction-driven wheel responsible for generating wheel squeal. Squeal noise generating mechanism has been examined under the laboratory condition. Model rig of the rail and the wheel are made and influential parameters to squeal noise e. g. frictional force, normal force between the rail and the wheel, creep speed of the wheel have been measured and calculated. Negative damping characteristic curve are calculated currently. Necessary relating computational analysis has been carried on also.
