This paper presents an original methodology of parametric optimization of the railway vehicle
bogie with elastic wheels. The approach to optimization is based on the mathematical modelling
of the bogie in perturbance coordinates with respect to operational state of static equilibrium
and on the calculation of the dynamic response caused by geometric irregularities of the track or
running wheel surfaces. Two types of objective functions has been formulated for the problem
of dynamic load minimization. The first type is based on power spectral density functions and
the second type on amplitude characteristics of the dynamic forces transmitted by rubber silent
blocks between engine stators with gear housings and the bogie frame and the dynamic forces in
contact between rails and wheels in a vertical direction. These couplings transfer great dynamic
forces caused by considered kinematic excitation which essentially influences a service live of
the wheelsets, rails and support of engine stators.
