A vehicle body, two bogie frames and two wheelsets for each bogie frame are used to describe the railway vehicle model. The system dynamic is modeled using a 38-DOF system including the longitudinal, lateral, vertical, roll, pitch and yaw displacements. A heuristic nonlinear creep model and the elastic rail are used to simulate the wheel-rail contact. Stable movement and the corresponding limit...

Gaining insight into possible vibratory responses of dynamical systems around their stable equilibria is an essential step, which must be taken before design and application. The results such a study can significantly help prevent instability in closed-loop stabilized by avoiding the excitation system neighborhood its resonance. This paper investigates nonlinear oscillations rotary inverted pen...
