Abstract
In order to ensure the safe operation of EMU in the harsh wind environment and extreme temperature conditions, the research studied the temperature in the equipment cabin of high-speed train when it travels at 250km/h to pass through the wind zone, where the environment temperature is 45℃ and the velocity of crosswind is 20m/s. The results show that the temperature in the equipment cabin rises obviously, and the maximum temperature is nearly 89℃ appearing at the top of the traction converter of head car. It is of guiding significance for the location of air inlet in the equipment cabin and the setting of the air duct.
