ABSTRACT:
A damping apparatus for large structures operable both passively and actively is disclosed which comprises a passive type damping mechanism to be mounted on the structure and including an added mass, spring, dampener, etc., hydraulic cylinders mounted on the structure and connected to the added mass, an electro-hydraulic servo mechanism to switch the hydraulic cylinders between passive and active type operation, and a control unit for switching the electro-hydraulic servo mechanism between passive and active type operation in response to the velocity and displacement of the added mass as well as the velocity of the structure.
