The paper deals with forced vibration of Euler-Bernoulli beam with variable cross-section equipped with a distributed dynamic absorber. The beam is subjected to the concentrated and distributed harmonic excitations. The problem is solved using Galerkin’s method and Lagrange’s equations. Performing time-Laplace transformation the displacement amplitude of arbitrary point of the beam may be written in the frequency domain. The aim of the paper is to find the effectiveness of the distributed vibration absorbers in beams. As an example numerical results of vibration reduction in wind turbine’s tower are presented.
