6 FAQs about [Hollow shaft of wind turbine generator]

Can lightweight rotor shaft design be used in a wind turbine?

Through the application of the lightweight design methodology to the rotor shaft for a wind turbine, 20% material could be saved in the trumpet section of the optimized hollow rotor shaft in comparison to the raw design, but with fulfilment of the failure criterion.

What is a wind turbine rotor shaft made of?

The stated potential of GJS manufactured in permanent metal moulds and its unknown specific material properties led to the research project “Gusswelle”. The main objective is the optimization of design possibilities for wind turbine rotor shafts. Therefore, a raw hollow rotor design shaft made of EN-GJS-400-18-LT chill cast is developed.

What is the hollow rotor shaft design methodology?

The hollow rotor shaft design methodology is divided into different interdependent steps (Fig. 1 ). Involved in the design process are Fraunhofer LBF, Fraunhofer IWES and a participating foundry. Fraunhofer LBF determines the cyclic material behavior of EN-GJS-400-18-LT chill cast.

Can chill cast be used for wind turbine rotor shaft design?

The main objective is the optimization of design possibilities for wind turbine rotor shafts. Therefore, a raw hollow rotor design shaft made of EN-GJS-400-18-LT chill cast is developed. The project partner Fraunhofer LBF investigates the cyclic material behaviour of chill cast nodular cast iron.

What is optimized hollow rotor shaft?

Based on material investigations of EN-GJS-400-18-LT chill cast, an optimized hollow rotor shaft is developed. The design process and the resulting shaft design are presented. The optimized hollow rotor shaft prototype will be tested on a full-scale test bench to validate the design methodology.

Is inner ring creep relevant for hollow rotor shafts of wind turbines?

Therefore, inner ring creep is highly relevant for hollow rotor shafts of wind turbines with thin walls and low contact pressure. The prediction methodology for inner ring creep used in this case is based on the finite element simulation of the main shaft fatigue test bench.
