This contribution presents a method of dynamic analysis of a railway vehicle bogie which is based on the statistical approach. The excitation caused by vertical track irregularities is supposed. Using the linearized model of adhesion characteristics between wheels and rails and torque characteristics of engine, the complete mathematical model of vehicle bogie is transformed into the frequency domain. The dynamic response is expressed by upper limits of deformations and forces transmitted by couplings calculated using spatial power spectral densities of the track irregularities. The methodology is applied to a particular railway vehicle bogie with two individual wheelset drives excited by track irregularities measured along the track for left and right rails, respectively.
