Description: Higher travel speeds of rail vehicles will be possible by developing sophisticated top performance bogies having creep-controlled wheelsets. In this case the torque transmission between the right and the left wheel is realized by an actively controlled creep coupling. To investigate hunting stability and curving capability the linear equations of motion are written in state space notation. Simulation results are obtained with realistic system parameters from industry and various controller gains. The advantage of the ?creep-controlled wheelset" is discussed by comparison the simulation results with the dynamic behaviour of the special cases ?solid-axle wheelset" and ?loose wheelset" (independent rotation of the wheels). The stability is also investigated with a root-locus analysis.
