    摘要: A vibration control system for a rotary machine having a rotor, includes a sensor disposed within the rotary machine for sensing vibration of the rotor, a vibration damping device disposed within the rotary machine for imparting a reaction force to the rotor, and a controller arranged in operable communication with the sensor and the vibration damping device. The controller is adapted to receive a sensor signal from the sensor and to send a control signal to the vibration damping device for damping the vibration of the rotor.

    摘要: An engine mount structure is provided with active vibration mechanisms which are attached in the vicinity of the engine mount to prevent engine vibrations from propagating into the engine mounting structure, for example, the wing or fuselage structure of an aircraft. Additionally, sensors are provided on the engine and/or wing/fuselage structure to provide control signals to the active vibration mechanisms so that the active vibration mechanism react to the sensed data to minimize the vibration transmissibility from the engine into the wing/fuselage.

    摘要: A wind turbine lattice tower structure includes a plurality of structural members connected together to define an open lattice tower, with the structural members including vertical leg members and diagonal braces extending between the vertical leg members. Pairs of the diagonal braces form cross braces having an intersection point therebetween. A damping bolt connection assembly is provides at the intersection point of the cross braces and is configured to attach the cross braces together at the intersection point while providing for relative movement of each individual cross brace along a defined longitudinal section of the other respective cross brace.
