We’ve previously looked at the role of the rail track and wheels in inducing vibrations in trains – (see: Railway vibrations – part 1 – Graunching ) now it’s time to turn to the effect of vibrations on the rail passengers themselves. Dr. David Bissell – a lecturer at the Australian National University’s College of […]

Railway vibrations – part 1 – ‘Graunching’.
One of the first technical papers to reference ‘Graunching’ was ‘Railway Noise: Curve Squeal, Roughness Growth, Friction and Wear’ (Report: RRUK/ A, 2003, D.J. Thompson, A.D. Monk-Steel, C.J.C. Jones. P.D Allen, S.S. Hsu, and S.D. Iwnicki) “Other related forms of curving noise include ‘graunching’ at switches and crossings (possibly due to flange rubbing), [and] ‘juddering’ […]

In 1972, Michael A Tainsh published a monograph called Oscillation of Human Performance as a Personality Measure, in the journal Perceptual and Motor Skills. Tainsh […]
