Output-Only Structural System Identification Based on Symplectic Geometry Mode Decomposition

Volume 1, 2021
In this paper, a novel output-only structural system identification method is proposed based on the decomposition of the response signal by applying newly developed symplectic geometry mode decomposition (SGMD). The SGMD can decompose the output signal

Symplectic period mode decomposition method and its application in fault diagnosis of rolling bearing

Journal of Vibration and Control, 2023
The rolling bearing fault signals are accompanied with the specific periodic impulse components in case of fault. Due to the background noise, the periodic impulse component is extremely weak and difficult to be extracted.
