This paper investigates the control effects of sandwich beam to random excitation. The statistical properties of the transverse displacement and stress are analyzed. The control effects of the damping layer (including the viscoelastic layer and the constraining layer) on random transverse displacement and random stress are investigated. The results for a sandwich beam are compared with those for the original beam. Finally, examples are given to illustrate the method.
