| Research Abstract |
The purpose of this study is to establish the efficient and robust method to suppress vibration of tension stabilized structures such as a cable or a membrane. We especially noted vibration absorbers that absorb vibration of a main structure by harnessing resonant phenomena. Our major results are to build a new robust optimization method and to realize a self-sensing vibration control method using a microcomputer. These results make the vibration absorbers overcome their drawback and establish the more efficient and more robust method to damp vibration of tension stabilized structures.
