Planet carriers in wind turbines

Fracture mechanical tests on planet carriers from wind turbines
Planet carrier


Proof of component safety of planet carriers at low temperatures (planet carriers are made of high-strength cast iron GJS 700 with low ductility to save weight)


Development of a simple method and a VDMA guideline for the practical implementation of a safety analysis


Adaptation of fracture mechanics methods according to British Standard (BS7910) for the static and dynamic (cyclic) verification and definition of adapted boundary conditions for this verification; conversion of the methodology into a VDMA guideline (project implementation in cooperation with the VDMA Working Group Planet Carriers)
