Study on fault diagnosis method for planetary gearboxes based on optimized VMD and ELM

ObjectiveDue to the complex structure of planetary gearboxes, fault features are difficult to extract, and traditional methods rely heavily on professional expertise. To solve these problems, a fault diagnosis method integrating beluga whale optimization (BWO) algorithm optimized variational mode de...
