STUDY OF THE LATERAL STABILITY OF A BOGIE

This study permits a mathematical model to be found representing the movements of free bogie supporting a given load and running on a straight track of good quality. Starting from this model, it is possible to show the influence of the principal structural-design features of a bogie on its critical speed, namely: (1) characteristics of the connections between bogie-frame and axles; (2) bogie wheelbase: (3) sprung mass: and (4) equivalent conicity characterising the geometry of the contact between rail and wheel. This study has permitted the optimization of the choice of constructional characteristics of the bogies of the SNCF TGV 001 trainset.
