Analysis of spatial vibration of high-speed train and slab track system under cross-wind

Wind fences can reduce aerodynamic force of railway vehicle in the cross-winds,and the performances of wind fences might be affected by many factors.

Based on the test data of wind-tunnel test done on the commuter vehicles by the railway departments in the foreign countries,under the condition of single track and multiple tracks on the embankment,the paper tries to analyze and compare the problems that are about the main factors influencing lateral force of(vehicle) in the cross-winds and the fence for protection against wind.
