DAMPER AND DAMPING STRUCTURE FOR A WAVE ENERGY CONVERSION DEVICE

摘要

The present invention relates to a damper for damping the reactionary motion of a wave energy conversion device (1) to wave motion, comprising a damping energy absorber (7) having a reversible non-linear stress-strain response, arranged to damp the reactionary motion of the WEC. According to a first aspect, there is provided a damping structure (2) for a wave energy conversion device (1). The structure comprises a fixed member (S), and a damping member (7) having a reversible non-linear stress-strain response. The damping member (7) is connectable between the fixed member (6) and a moveable member or float (3) of a wave energy conversion device (1). The invention also relates to a wave energy conversion device (1).
