... train was analyzed to investigate the time-domain characteristics of the creepages and creep forces caused by the curved sections. The frequency region, where the flexible dynamic behavior of a wheel is unstable and the occurrence time of the unstable dynamical behavior match well with the results...

...Sen-Yung Lee; Yung-Chang Cheng A new dynamic model of railway vehicle moving on curved tracks is proposed. In the new model, the motion of the car body is considered and the motion of the truck frame is not restricted by a virtual boundary. Based on the heuristic nonlinear creep model...

...Sen-Yung Lee; Yung-Chang Cheng Based on the heuristic nonlinear creep model, the nonlinear coupled differential equations of the motion of a ten-degree-of-freedom truck system, considering the lateral displacement, the vertical displacement, the roll and yaw angles of the each wheelset...

...F. Divo´s; T. Tanaka [S0739-3717(00)01401-X] We defined a creep parameter (η ′ ) in order to analyze the effect of creep on E determination as: (4) η ′ = E t − E 0 E 0   100 where: E 0 : reference modulus of elasticity...
