Transfer path analysis (TPA) is a kind of system level solution based on test engineering and data. As a comprehensive way of understanding vibration noise problem, the method of transfer path analysis can be more comprehensive and systematic in fault diagnosis of vibration and noise problem. Several mainstream analysis methods of transfer path analysis are expounded briefly, and then the role of OPAX load identification method in the transfer path analysis is mainly introduced, and applied in the process of trying to solve vehicle interior noise rumble. And its effective screening optimization effect is verified by tests of actual working condition.
