Project Details
Description
In relation to specific high-dimensional parameter dependent nonlinear dynamic systems - mainly models of moving railway vehicles - the dynamics of the systems is examined, and the qualitative behaviour investigated. Since the models are rather complicated, the analysis is carried out numerically, and some results verified through analytic investigations of simple model examples. The results are applied to actual railway vehicles, and have demonstrated their ability to predict accurately the critical speed, at which a railway vehicle may change its stable equilibrium state from steady motion along the track center line, to a motion along the track combined with a lateral oscillation. Chaotic motion has been predicted, and recently confirmed by japanese scientists.
