ABSTRACT: There exists a variety of oscillation modes in the Sub-Synchronous Resonance (SSR). The trend of its development cannot be judged by the existing detection methods. This paper presents a stability diagram and the matrix based beam SSR new method for vibration modal identification. This method does not need to explicitly use SSR, and the mechanism of directly using the test data is identified. First, it is established by the method of stable figure order number in the system. Then use the matrix of precise ...
