The reduction of the noise generated by traction motors used in railway applications has become a very important criterion during their design phase. The overall noise comes from three main sources, of vibrational, aerodynamic and magnetic natures. Among these contributions, aero- dynamic noise is dominant at high rotation speeds. It is generated by the ventilation system of the motor. The use of numerical simulations to predict this noise can be very expensive and time-consuming when several geometrical parameters need to be tested. Analytical methods are suitable at the early design stage, due to their low computational time. This work is dealing with the analytical modelling of sound generation and propagation inside the ventilation syst...
