Time–frequency extraction model based on variational mode decomposition and Hilbert–Huang transform for offshore oil platforms using MIMU data

Time–frequency extraction is a key issue to understand structural symmetry of dynamic responses of offshore oil platforms for early warning during drilling operations. Current popular methods for signal characteristics extraction can only obtain the attributes with a single dimension or poor precisi...
