Abstract
A strut assembly includes an axially elastically extensible tube having attachment means at each end and an axially extensible actuator attached within the tube and between its ends so that reciprocal axial extensions of the actuator cause elastic longitudinal displacements of the strut assembly. Such a strut assembly is particularly useful for transmitting operational loads between parts of a structure and for inputting periodic loads into one of the parts as part of an active vibration control system.
