On the problems of lateral force effects of railway vehicles in S-curves

This paper deals with the lateral force effects of conventional four-axle railway vehicles in conditions S-shape curves, which are represented especially by switches negotiated diverging direction. With use a multi-body model an electric locomotive, sensitivity analysis selected vehicle parameters on maximum guiding S-curve is performed. Subsequently, definition so-called equivalent proposed. simplified parameter can be used for purposes quantification damaging switches, e.g. wear-dependent track access charge systems. Attention also paid to particularities systems active radial bogie or wheelset steering tight S-curves and relevant requirements these The problem punctual on-board recognition demonstrated using experimental data measured locomotive.
