FEA Computations Applied to Engine Cooling Fans 2000-01-0968
In an effort to model a complete engine cooling module, Valeo has developed static and dynamic FEA models for its engine cooling fans. The static FEA analysis has led to a significant fan weight optimization for constant Van Mises stresses and ring deflection (a 15% reduction). Both experimental and numerical results have stressed the importance of the model of the interface between the motor and the fan in the dynamic FEA modal analysis. Moreover, the main engine cooling fan modes have been identified for the first time.
