Research on Motor Vehicle Aerodynamics for 17t-axle-load Centralized Power EMU

Abstract

This text takes the Motor Vehicle of 17t-axle-load Centralized Power EMU as the object for research and uses the Computational Fluid Dynamics (CFD) method to calculate and analyze the aerodynamic drag, aerodynamic lift and moment of force at each direction of the train in the condition of steady state running without cross wind and steady state running with cross wind, and makes an evaluation of the aerodynamic performance of the train by comparing it with that of existing trains.
