Frequency response function-based transfer path analysis using virtual parameters

This study suggests the concept of virtual parameters to perform a transfer path analysis (TPA) for a vehicle. Existing conventional TPA methods are easily affected by measurement errors and experimental complexity. The proposed method uses a dynamic substructuring model to overcome the complexities induced by a conventional TPA method. In this process, the concept of virtual parameters is introduced to replace the fixed boundary condition. The proposed method is validated by experiments conducted on a vehicle component.
