Abstract: The invention is a frame for carrying a load in a wind turbine. The frame comprises a first and a second beam extending in a lengthwise direction, a third beam extending in a transverse direction between a first joint on the first beam and a second joint on the second beam. The third beam is configured for carrying the load. The frame further comprises a stress-inducing cross-shaped structure forming four legs joined at an intersection and extending therefrom towards four ends, where two of the four ends are attached on opposite sides of the joint on the first beam and the other two of the four ends are attached on opposite sides of the joint on the second beam. To prevent excessive deflection of the third beam and of the cross-shaped structure, the cross-shaped structure is decoupled from the third beam and therefore allowed to move e.g. without touching the third beam.

Abstract: A nacelle of a wind turbine, the nacelle comprising a rear frame structure (1) comprising a plurality of truss members (2), and a plurality of pivot joints (3). Each pivot joint (3) interconnects ends of at least two truss members (2), thereby forming a truss structure with the pivot joints (3) arranged in node points of the truss structure. At least some of the pivot joints (3) are adjustable in such a manner that an angle between two truss members (2) being interconnected via a pivot joint (3) is adjustable by means of the pivot joint (3). Nacelles of varying dimensions can be provided using a limited number of basis components in the form of truss members (2) and pivot joints (3). The pivot joints (3) are moment neutral, and therefore bending moments are not introduced into the truss members (2).
