Latest Patents

Dayang Li holds a patent for a "Damage identification method for cantilever beam based on multifractal spectrum of multi-scale reconstructed attractor." This method involves acquiring an original acceleration signal of the cantilever beam through a dynamic measurement system. It includes performing stationary wavelet decomposition on a pretreated acceleration signal to obtain multi-scale sub-signals. The process selects the multi-scale sub-signal that represents the main vibration characteristics of the cantilever beam for phase space reconstruction and normalization. The multifractal spectrum of the multi-scale reconstructed attractor is then constructed, establishing a damage index based on a singularity index of the multifractal spectrum. This method quantifies structural damage characteristics in the multi-scale phase space domain and provides a simple, rapid, and accurate damage identification method for cantilever beams.
