MATHEMATICAL MODELS AND CALCULATION METHODS IN THE STUDY OF LATERAL DYNAMICS OF RAILROAD CARS

MODELLI MATEMATICI E METODI DI CALCOLO NELLO STUDIO DELLA DINAMICA LATERALE DEI VEICOLI FERROVIARI

The conditions affecting lateral dynamics of railroad cars, such as axle-box guides and forces of pseudosliding, rail profiles and tires, are considered. Mathematical models of railroad cars are derived for an analysis of lateral dynamics. Both linearized and nonlinear systems are analyzed and results are optimized. Experimental results are compared as well. It is concluded that the theory of pseudosliding permits an improvement of the study of the lateral dynamics of railroad cars, both of the normal type with 2 or 3 axles, as well as of unconventional vehicles such as those with independent wheels or with active guide elements.
