..., FASTSIM algorithm developed by Kalker is used to determine the creep forces on the tread and flange of wheels ( 14 ). For more details on creep force models and implementations, one can refer to the literatures ( 15 16 ). In the assessment of railroad vehicle stability, the linear eigenvalue...

...Ali Afshari; Ahmed A. Shabana In some of the wheel/rail creep theories used in railroad vehicle simulations, the direction of the tangential creep forces is assumed to be the wheel rolling direction (RD). When the Hertz theory is used, an assumption is made that the rolling direction...

...Hiroyuki Sugiyama; Yoshihiro Suda In this investigation, contact search algorithms for the analysis of wheel/rail contact problems are discussed, and the on-line and off-line hybrid contact search method is developed for multibody railroad vehicle dynamics simulations using the elastic contact...

...M. Tanabe; N. Matsumoto; H. Wakui; M. Sogabe; H. Okuda; Y. Tanabe In this paper, a simple and efficient numerical method to solve for the dynamic interaction of a high-speed train and railway structure during an earthquake is given. The motion of the train is modeled in multibody dynamics...

...Federico Cheli; Roberto Corradi; Giorgio Diana; Alan Facchinetti Tramcar vehicles significantly differ from traditional railway vehicles for both the adopted structural configuration and design solutions and the operating conditions. For this reason, a new numerical model specific for the analysis...

...Cheta Rathod; Ahmed A. Shabana In railroad vehicle dynamics, Euler angles are often used to describe the track geometry (track centerline and rail space curves). The tangent and curvature vectors as well as local geometric properties such as the curvature and torsion can be expressed in terms...
