Moving Train Model Experiment Study on the High Speed Railway Chamber Windbreak

Moving Model Test of High-Speed Train Aerodynamic Drag Based on Stagnation Pressure Measurements

A moving model test method based on stagnation pressure measurements is proposed to measure the train aerodynamic drag coefficient. Because the front tip of a high-speed train has a high pressure area and because a stagnation point occurs in the center of this region, the pressure of the stagnation point is equal to the dynamic pressure of the sensor tube based on the obtained train velocity. T...

Strength Analysis and Experiment of High Speed Railway Gearbox Bracket

Light-weighting of high speed railway equipments has become a major trend, which leads the upgrades of equipments. A new C-shaped bracket has been produced to connect the driving gearbox with the bogie. This paper built a three-dimensions model of a C-shaped bracket, got the maximum and distribution of the stress and deformation under two different working conditions form finite element analysi...
