EN This paper is devoted to the study of the influence of random variation of model parameters of a beam with viscoelastic layers on the probabilistic characteristics of its natural frequencies and dimensionless damping coefficients. The relationships between the model parameters and the dynamic characteristics of the beam were approximated by quartic polynomials based on the results of calculations using FEM, where beam finite elements were used, taking into account the beam lamination. The nonlinear eigenproblem was solved using the continuation method. The calculation results for an example laminated beam are presented.
