Integrated gearboxes

As noted in Section 6.11.1, the cases of integrated gearboxes must be very robust, in order to transmit the rotor loads to the nacelle structure without experiencing deflections which would impair the proper functioning of the gears. In view of the complex shape of the casing, stress distributions due to each load vector usually have to be determined using finite-element (FE) analysis - these can then be superposed in line with the different extreme load combinations. The fatigue analysis will require the superposition of stress histories resulting from simultaneous time histories of rotor thrust, yaw moment and tilt moment derived from simulations at different wind speeds.

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
