Abstract :
The theory of transfer path analysis (TPA) and its limitations are reviewed. An innovative unbiased estimation methodology of transfer function is introduced and applied. The measurement method of transfer function is improved. Then TPA of a car, using the data of easy measurement in operational condition of vehicle, can be put in practice for analyzing vibration transmissibility from engine transmitting to compartment. Accuracy of transfer function is improved, the process of measurement is predigested, and measurement time also is shorted. The effectiveness of the proposed approach is validated by the results. A data post-processing program of measurement specialized in estimation and analysis is developed.
