Construction of seated passenger model on high speed railway vehicle by multi-body dynamics

Lateral Stability Analysis of High-Speed Railway Vehicle on Curve

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...

Bifurcation Analysis of High-Speed Railway Vehicle in a Curve

In order to prevent unpleasant incidents, preservation high-speed railway vehicle stability has vital importance. For this purpose, railway vehicle is modeled using a 38-DOF. This paper presents an investigation on limit cycle and bifurcation of high speed railway behavior. It is revealed that the critical hunting speed decreases by increasing the wheel conicity. Also the critical hunting speed...

A model for the coordination between high-speed railway lines and conventional rail lines in a railway passenger transportation corridor

With the construction of high-speed railway lines in China, there are growing concerns about the rational transport cooperation between high-speed railway lines and conventional rail lines. A rational transport cooperation scheme can improve railway capacity utilization, train speed, service and the organization quality of railway transportation. The previous research mainly focused on the aspe...

An Active Stability System for a High Speed Railway Vehicle

— This paper describes an active stability control system for a high-speed railway vehicle. The complete design process is described, starting with generating mathematical models of the system for control system design and for system validation. The control strategy is briefly outlined along with the necessary refinements required for practical implementation. Some brief results for the stabili...
