Stability Evaluation on Aerodynamics of High Speed Railway Train

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...

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...

Intelligent Train Scheduling on a High-Loaded Railway Network

We present an interactive application to assist planners in adding new trains on a complex railway network. It includes many trains with different characteristics, whose timetables cannot be modified because they are already in circulation. The application builds the timetable for new trains linking the available time slots to trains to be scheduled. A very flexible interface allows the user to...
