Articulation support shaft (p-train): the effect of its flexibility on power car resonant modes (IM-DA-116)

This memo is a sequel to IMDA 112 which investigated the effects of articulation joint support shaft flexibility on the resonant modes of E-train power car(1). The same mathematical model was used, but with the following changes: Mass 30 Tons (27.2 Tons for E-train P.C.) Body free-free frequencies...
