Abstract: In this paper, the railway vehicle is modeled by a seventeenth-degrees-of freedom full vehicle model to investigate the elastic vibrations of the railway vehicles's car body subjected to the excitations from vertical track irregularities. These irregularities are represented by the power spectral density functions which are authenticated for the stochastic real track data collected from the Konya-Polatli railway line in Turkey. The car body floor is modelled as a structure consisting of a plate and its connecting components by introducing artificial springs at the joint points. The model can express the complicated elastic vibrations with fewer degrees of freedom and at a lower computational cost than the detailed finite element model. To suppress the vertical vibration of the flexible-bodied railway vehicle secondary suspension control design based on affine parameter dependent model has been built with a single objective function and the solutions are obtained via H-infinity optimization. The numerical results show that the complicated mode shapes can successfully be expressed analytically and the simulation studies illustrate that the active system is effective in reducing both the flexible and rigid modes of the car body and improving the ride comfort.
