Abstract. This paper considers the modelling of wind turbine main bearings using analytical models. The validity simplified representations used in existing work is explored by comparing main-bearing force reactions with those obtained from higher-fidelity 3D finite-element Results indicate that there good agreement between and models case a non-moment-reacting support (such as for double-row s...

This study proposes a statistical approach based on vibration energy at damage to detect multiple damages occurring in roller bearings. The analysis was performed four different rotating speeds—1002, 1500, 2400, and 3000 RPM—following damages—inner race, outer ball, combination damage—and under two types of loading conditions. These experiments were SpectraQuest Machinery Fault Simulator™ by ac...

Self-aligning roller bearings are an integral part of the industrial machinery. The proper analysis and prediction various faults that may happen to bearing beforehand contributes increase in working life bearing. This study aims at developing a novel method for self-aligning as well automatic classification using artificial neural network (ANN) deep (DNN). vibration data is collected six diffe...

The fault quantification of a tapered roller bearing (TRB) can provide reliable guide for predictive maintenance. Currently, damage size estimation based on vibration signals has been proposed and developed. However, most approaches are focused the theory ball bearings. Unlike point contact bearing, between raceway is line contact. So, current practices micro-motion bearings limited when estima...

In order to study the elastic contact fatigue problems of composite cylindrical roller bearing, through three stages crack initiation, propagation, and ablating bearing theoretically analyzed, subsurface stress is one factors damage. By finite element method theoretical analytic with solid surface, size distribution shear are comparing calculation results two methods, comparison show that calcu...
