The life and reliability of integrated transmission device may be significantly affected by the vibration,harshness and quality of the device. The relationship between the internal excitation and vibration of the device is one of the important research works. An experimental scheme is presented to obtain the relationship between the internal excitation and vibrations of an integrated transmission device. A coupling signal analysis method is also proposed to investigate the signals from the multiple measurement points and experimental conditions. The relationship between the internal excitation and vibration of the device is obtained based on the proposed experimental method,which can provide some guidance for the structure optimization of the device. The results show that the experimental analysis method can be used to not only determine the vibration source location of the integrated transmission device,but also find the dominant frequency which should be controled,which can provide some guidance for the structure optimization of the device.
