Digital analysis of the free-free bending vibrations of a
propeller shaft and a beam-type rear axle are compared, for different
theoretical models, with the results of rig tests. The relative importance
of distributed mass, the coupling between the bending and
torsional modes and the half shafts of the rear axle are discussed.
The relation between the work completed and the programme of work in
progress is given briefly at the end of the report
