A simplified vertical resonance test of a Leyland R3 type body structure (IM-DOS-096)

During the limited track testing of the R3 vehicle supplied to F.R.A., the vertical vibration response at frequencies around 10 Hz was more pronounced than that measured on the original L.E.V. vehicle. As time did not permit investigation of this on the F.R.A. R3 vehicle. a structural resonance test was...
