ABSTRACT
The benchmark simulations were done using the package ADAMS/Rail with mainly the MEDYNA solver. The vehicle model was built up starting with a parameterised bogie, shown in, taken by the ADAMS/Rail model library Only coordinate systems of wheel-rail interconnection elements are oriented in a different way. Direction of creep forces and creepages, given in contact coordinate systems are oriented similar to the wheel/rail interconnection element systems. On the left side the longitudinal axis is oriented in the direction of travelling speed. On the right side it is orientated opposite to travelling speed. Influence of angle of attack on contact line is taken into account, computing the projection of the wheel in plane 2,3 of rail coordinate system. Stability is solved using two different methods. Linear stability using eigenvalue method and quasilinearisation for wheel-rail contact, numerical integration in time domain.
