- Summary:
- E-motors are characterized by their high-frequency content. This brings a new challenge for a technology such as Component-based Transfer Path Analysis.This paper will intend to show how this methodology has been applied for a wiper e-motor. The source is characterized in-situ by a set of blocked forces.A dedicated high-frequency shaker was developed to meet the required data quality.Afterward, the independent loads are converted to contact forces using a Frequency Based Substructuring technique, allowing assembly definition and target prediction on a different receiver. The substructuring technique is validated on a wide frequency range up to 8kHz. Finally, the predicted vibrations on the target assembly are compared to the measured one for validation purposes
