The mine hoist sheave bearing is a large heavy-duty bearing. located in a derrick of tens of meters. Aiming at the difficulty of sheave bearing fault diagnosis. a combined fault-diagnosis method based on the improved complete ensemble EMD (ICEEMDAN) energy entropy and support vector machine (SVM) optimized by artificial fish swarm algorithm (AFSA) was proposed. https://parisnaturalfoodes.shop/product-category/d-mannose-powder/
