Experimental Research of Intelligent Active-Member for Self-adaptive Deployable Structures

A new type of intelligent active-member with the functions of sensation and actuation was designed and manufactured for the self-adaptive control of deployable structures. The performances of displacement and force outputs of the active-member, as well as its dynamic response, were investigated experimentally, and its displacement and force gains under different frequencies of input voltage were obtained. The experimental results show that the active-member can be used for eliminating joint clearance, precise positioning and suppressing structure s vibration.
