The harmonic signal will affect the identification of the working mode of the structure, and the identification of the harmonic signal can be used as the identification of the micro-vibration source. In this paper, according to the difference between the statistical characteristics of the system response and the harmonic response, a kurtosis value method based on random variable is applied to identify the harmonic response. The effectiveness of the method is verified by the simulation and the vibration data results of Shenzhen Sager Tower, which provides a new method for eliminating the influence of harmonic response in the following working modal parameter identification and vibration source identification of synchrotron radiation device.
