Disclosed are a train compartment vibration monitoring method, a vibration signal feature library establishment method and a vibration signal feature library application method. A non-invasive train compartment vibration monitoring method is used, and only a vibration signal of an overall measurement point in a train compartment needs to be acquired during actual monitoring, such that sensor redundancy is avoided, the cost is reduced, and the weight reduction of a train is facilitated; the relationship between a vibration source position and phase shifting and amplitude attenuation is reflected accurately and truly, and a vibration situation of an unknown vibration source can be monitored; an abnormal vibration of a vibration source can be recognized, thereby providing a basis for abnormal vibration processing; and the reconstruction of a vibration source signal can be realized on the basis of only measuring the vibration signal of the overall measurement point, such that the real-time update of a multivariate vibration signal feature library is realized, and the multivariate vibration signal feature library can provide a data basis for vibration signal optimization decomposition, vibration signal image recognition, abnormal vibration signal recognition, etc.
