Title: COUPLING DEVICE, SUPPORT STRUCTURE AND METHODS
Abstract:
Coupling device (10) comprising two support members (12); a joint (14) connecting the two support members (12) and allowing relative rotation between the support members (12) about at least one rotational axis (20, 22); and at least one damping element (24) connecting the two support members (12) in parallel with the joint (14); wherein the at least one damping element (24) is configured to deform plastically by a relative rotation between the support members (12) about the at least one rotational axis (20, 22). A support structure (36) for supporting a mass, a method for adjusting the stiffness of a coupling device (10) and a method for providing stiffness to a coupling device (10) are also provided.
