摘要： An apparatus for actively damping vibrations in an element (30) which is secured to a support (28) comprises: an actuator (10, 40) locatable at a point adjacent to the point of attachment (29) of the element to the support and operable to apply force between the element and the support. A sensor (34) is associated with the element to produce a signal in response to vibration of the element and control means (36) is provided to operate the actuator in response to said signal to apply a force to the element to damp vibrations therein.
