E-motor: Source Characterization and Target Prediction up to 4.5kHz Using Component-Based TPA 2021-01-1060
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 modular methodology has been applied for a wiper e-motor. The source is characterized in-situ by a set of blocked forces and alternatively with pseudo forces.
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. Finally, the predicted vibrations on the target assembly are compared to the measured one for validation purposes.
A dedicated high-frequency shaker was developed to meet the required data quality. In this way the substructuring technique was applicable in a wide frequency range up to 5 kHz.
