Viscoelastic damper assembly

A viscoelastic damper assembly (100) comprising:

• a housing (110) provided with an opening (111) at a first end thereof and provided with a first connection device (120) at a second closed end thereof,
• at least one damping unit (140) having a first end arranged to a second connection device (150) and a second end extending into the housing (110) via the opening (111),
• a resilient sealing means (160) providing an airtight and watertight seal between the at least one damping unit (140) and the housing (110),
• a compensation means (170a, 170b, 171) for compensating interior volume, wherein
• the first and second connection devices (120, 150) connect the viscoelastic damper assembly (100) to a stationary object or structure (410) at one side and to an object or structure (400) to be damped at another side,
• a viscous fluid (130) is accommodated in the housing (110),
• the housing (110) is partly filled with the viscous fluid (130) and partly filled with an immiscible filling fluid (131),
• the at least one damping unit (140) extends at least partly into the viscous fluid (130),
• the at least one damping unit (140) is formed by an elongated body (140a) and at least one damping device (140b) comprising at least two damping members (142a-142d),
• the at least two damping members (142a, 142b) are arranged to each other or to a base structure (143),
• the at least two damping members (142a-142d) are aligned horizontally or vertically,
• geometries of the at least two damping members (142a-142d) are repeated in a rotational or translational manner, and
• the housing (110) is arranged with the opening (111) downwards and wherein the immiscible filling fluid (131) has higher density and lower viscosity than the viscous fluid (130).
