This paper proposes vibration suppression design 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∞ 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.
