Transfer path analysis and its application to diagnosis for low-frequency transient vibration in the automotive door slamming event

Transfer path analysis (TPA) method has been widely used in the frequency-domain applications. However, it is not suitable for transient vibration problems such as the abnormal vibration in the automotive door slamming event. In this paper, two time-domain TPA models are used for the abnormal transient vibration diagnosis in the automotive door slamming event whenever the door glass is located at its lowest location. To obtain the excitation...
