Outline of Final Research Achievements |
The aim of this research is to realize highly efficient and robust vibration control method of truss structures. In this research, the following three issues were conducted. (1) Robust optimizations and vibration control experiments of a both-clamped beam structure by using multiple piezoelectric vibration absorbers s system. (2) Modeling and optimum design of a truss structure including piezoelectric vibration absorbers s system. (3) Vibration control experiments of the truss structure. These study revealed that the proposed identification method, robust design method, and vibration control method were useful.
