Abstract
One of the crucial parts in wind turbine is Hub, which experience the loads from the blades and the loads were transmitted to the main shaft.
In this Design and Finite Element Analysis of Wind Turbine Hub project extreme loads and fatigue loads cases (IEC loads) were taken in to consideration and analysis are done for the two different materials viz cast iron and aluminum alloy.
Existing material is Cast Iron GGG 40.3 which has disadvantages like Very expensive Material for casting , Cost of Material is so High, Weight of the Hub is huge. In the Existing Material we have so many disadvantages, so that to overcome we have chosen the alternative material as Aluminum Alloy 6061.
Which has Advantages like Strength to weight ratio, Gradual Reduction in cost, Reduction in the weight of the hub.
Finite element analysis is used to compare the above materials with extreme and fatigue load condition as per IEC load are discussed in this Design and Finite Element Analysis of Wind Turbine Hub project.
