The effect of body flexibility on the lateral stability of the 2 axled A.P.T. coach (IM-APT-183)

Two modes of body flexibility were considered; fundamental lateral bending, and fundamental torsion. The fundamental torsion mode does not affect the lateral stability of the A.P.T. coach. The fundamental lateral bending mode coupled strongly with the wheel-sets to give another unstable region on the stability diaphragm. Figures 1 and 2...
