The paper is concerned with the problem of active reduction of torsional vibratio shafts. The solution based on application of a functionally graded material is preset The material of the shaft consists of two components - a passive host material, which be a laminate with strong shear stiffness, and active fraction in form of a piezoelei ceramic. One component gradually passes into the other according to the g exponential distribution. Three cases varying by the level of internal friction in the pas fraction are analysed in terms of the efficiency of the active approach. For mode natural damping in the matrix, best distributions of the active phase are found.
