Applied Load on Blade Bearing in Horizontal Axis Wind Turbine Generator

Rolling bearing life is typically calculated on the basis of its load ratings relative to the applied loads and the requirements regarding bearing life and reliability. Variation of applied load influences the load distribution in blade bearing directly and the load on maximum-loaded ball fluctuates with the applied load. Life of blade bearing is influenced by these variations eventually. Analysis and calculation method of applied load on blade bearing is illustrated by the case of a horizontal axis wind turbine.
