The effect of structural flexibilities on the vertical performance of the A.P.T. P train (IM-DA-140)

This memorandum describes the analysis of the vertical performance of a three vehicle A.P.T. P train, including the effects of articulation joint and body flexibilities. The vertical response to both random and discrete irregularities is investigated. Two possible modifications to the train are considered; (i) shortening the trailer vehicle (ii)...
