Experimental characterisation of railway wheel squeal occurring in large-radius curves

Fourie, Daniel Johannes; Grabe, Petrus Johannes; Heyns, P.S. (Philippus Stephanus); Frohling, Robert D. (Sage, 2016)

Tonal squeal noise (i.e. the high amplitude singing of a railway wheel with pure tone components) is emitted by some trailing inner wagon wheels on heavy haul trains in 1000m radius curves on the iron ore export line in ...
Frequency domain model for railway wheel squeal resulting from unsteady longitudinal creepage

Fourie, Daniel Johannes; Grabe, Petrus Johannes; Heyns, P.S. (Philippus Stephanus); Fröhling, Robert Desmond (Elsevier, 2019-04)

Railway wheel squeal is an unresolved noise pandemic facing the railway industry. Wheel squeal results from frictional self-excited vibration occurring in the wheel-rail contact. Solving the problem of squeal requires ...
