Vibration control of truss beam structures using axial force actuators

Abstract

The vibration control of truss structures has attracted increasing attention due to their possible use in space applications such as space station structures. Since the members of truss structures are s ubjected to axial force, a concept of vibration control by the use of axial f orce actuators is expected to give a new feature on vibration control of truss structures compared with the conventional external force c ontrol. The effectiveness of the concept is demonstrated through the numerical simulation of simple twodimensional truss beam, the model experiment of beam structure, and the corresponding simulation of ex~erimental beam model.
