The line modal testing was carried out for analyzing the modal parameters of the body structure of high speed train. The LMS test.lab, a famous noise and vibration test system, was used for data collection and processing. Based on the theory of modal parameter identification and the modal testing method under environmental excitation, the PolyMax modal extraction method was used and the elastic modal parameters and the corresponding vibration modes of the first three orders of the train’s body were obtained. This work may provide a reference for body structure optimization.
