This paper proposes optimal design of frame structures for vibration suppression in mechanical systems. The H_∞ norm of the transfer function from disturbance sources to the output points where vibration should be suppressed, is adopted as the objective function to represent the magnitude of vibration transfer. The design parameter is the cross-sectional areas of frame elements. For minimization of the H_∞ norm under the constraint of the total mass, a gradient method is employed, where the gradient vector is computed from the variation of H_∞ norm for small changes of suitable pairs of elements satisfying the mass constraint. An example is presented to demonstrate the effectiveness of the proposed design method.
