Optimal Distribution of Viscoelastic Material for Transient Vibration Suppression of a Flexible Beam

유연보의 과도 진동 감쇠를 위한 점탄성 재료의 최적 분포

Eigenvalues are taken as performance criteria for structural damping design using viscoelastic material. Given material properties, optimal distribution of damping material is sought based on eigenvalue sensitivity. For eigenanalysis of frequency dependent viscoelastic material rented structures, Golla-Hughes-McTavish(GHM) model is used and some dominant modes are chosen for consideration. (omitted)
