In this paper a parameter identification method for multibody systems is applied to a 1:5-scaled two-axled railway vehicle with conical wheels on a roller rig with UIC 60 roller profiles. The aim is to demonstrate how parameter identification in connection with constrained multibody systems and dynamical measurements can be performed

    The process of mathematical modelling and solution approach is described, where emphasis is laid on the structure of equations, modelling of the wheel-roller contact, numerical methods and the representation of the parameter identification method for the determination of the unknown stiffness and damping parameters as well as uncertain parameters like the coefficient of friction and manufacturing imperfections of the vehicle

    Additionally it is indicated that the 1:s-scaled railway vehicle can be utilized for running behaviour experiments with unconventional wheelset designs.
