The objectives of the study were to create finite element (FE) models for the engine front end accessory drive (FEAD) systems, to carry out normal mode analyses on the systems and to make a comparison of the predicted frequencies with those of measurement.
The analytical results of three FEAD systems showed that more accurate frequencies were calculated using the complete accessory model than the concentrated mass model. Therefore the complete accessory model should be created for structural analysis of the FEAD systems. It was also pointed out that great care should be taken in the creation of FE models.
