Ductile iron wind power generation device

What type of ductile iron is used for wind turbines?

These massive castings with varying wall thicknesses may contain a varying content of the ferrite precipitates scattered through the cross section of the casting. A common casting material used in the manufacture of parts for wind turbines is class GJS-400-18U-LT ductile iron.

Can ductile cast iron be used in wind turbines?

Future work will continue to integrate local material properties into strength assessment concepts of heavy-section castings used in wind turbines. The applicability of the approach needs to be validated by investigating other geometries and other austempered ductile cast iron grades.

What is a multi-domain optimization approach for cast iron components in wind turbines?

The presented multi-domain optimization approach for cast iron components in wind turbines is characterized by the combination of casting simulation, topology optimization, micromechanical analysis, and strength assessment (see Fig. 2 ). Thus, it uses cross-scale simulation and allows an enhanced consideration of local material properties.

Does ductile cast iron use local fatigue strength?

However, if the local utilization increases, the local fatigue strength within a component of austempered ductile cast iron becomes significantly more relevant. Local fatigue strength utilization using the results of shakedown analysis ( a) and FKM—fatigue strength ( b)
