| Abstract: | Piezoelectric active members,with load cells and actuating units built-in,can be usedas a kind of load-carrying components of truss structures. The application of the piezoelectric activemember developed by authors in vibration control of a truss structure was experimentally studiedin this paper.The obtained results show that the active member can be successfully used as an internal controller of the truss,to effectively improve modal damping and realize vibration control ofthe structure. |
