A generic wheelset structure is introduced allowing investigations with conventional as well as advanced unconventional wheelsets. The axles of this generic model can include variable camber angle and coupling. The coupling can be modelled rigidly or elastically, as a passive element with rotational damping or actively with creep control. The wheel profile is simplified by a dicone whereas the rail profile is that of a UIC 60-rail. Simulations are performed for the suspended single wheelset structure as well as for a simple bogie with two wheelset structures. The results indicate the influence of the parameters velocity, cone angle and camber angle on the tangent track response of several types of passive wheelset designs. For a bogie, so far beeing equipped with two conventional wheelsets, the simulation results are compared with experiments on a 1:5-scaled roller rig.
