Remaining useful life (RUL) prediction is a crucial mission for the Prognostic and Health Management (PHM) of machinery equipment in modern industry. In this paper, we use two different methods to predict degradation occurring in high-speed shaft bearing (HSSB) and predict the RUL using Artificial Neural Network (ANN) and Kalman Smoother (KS). To confirm the …

The high speed shaft coupling consists of flanges, torque limiters, a spacer, hub, and brake disk. The high speed shaft coupling was modeled in SolidWorks 2016, and a structural analysis was performed in the finite element analysis software ANSYS 19. Figure 2 shows the finite element model of the high speed shaft coupling.

When wind speed is near the cut-in wind (i.e. the lowest wind speed needed for power generation), the main shaft will be in lower speed (high speed shaft perhaps 1500 rpm). When the wind speed is higher than cut-in wind, the main shaft speed operates higher on the power curve, close to 1800 RPM, the Figure 3 shows the mean of speed shaft over ...
