Abstract：Aiming at the problem of severe vibration in a light bus, the transfer path analysis method is adopted to identify the main vibration sources of the vehicle. After analyzing excitation sources and simplifying appropriately, the transfer path model of vehicle vibration is established. Through the vehicle road test and indoor hammering test, the working condition data and transfer function data are obtained to determine the typical operation condition of vehicle vibration. The TPA module in Test. Lab is used to analyze the path contribution and then identify the main vibration sources. After comparing the load of the main vibration sources and the transfer function of the main vibration sources to the response points, it is confirmed that the severe vibration of the response points is due to the heavy load of the excitation sources.
