This paper proposes vibration suppression ds for adaptive truss structures which deform to achieve given tasks. The cross-sectional areas of members in the structure are optimized under a constraint of the total mass so that the vibration transmission from disturbance sources to specified points is suppressed. To measure the vibration transmission property, the H(index infinite) norm of the transfer function is adopted. The dynamics of the adaptive structure changes following the deformation, which is described by a nominal model and a perturbation term. For optimization, the simulated annealing is employed.
