    Аннотация The paper is devoted to study of the aerodynamic forces acting on flat cantilever beams per- forming flexural vibrations in a viscous fluid. Original method for the force evaluation is pre- sented based on analysis of experimental measurements of a logarithmic decrement of vibra- tions and relative variation in frequency of duralumin test specimens. The theoretical core of the method is based on the classical theory of bending beam oscillations and quasi-two dimensional model of interaction between a beam and a gas. Using the proposed method, extensive series of experiments for a wide range of oscillations parameters were carried out. The processing of the experimental data allowed to establish the global influence of the aero- dynamic effects on beam oscillations and the local force characteristics of each cross-section of the beam in the form of universal functions of dimensionless amplitude and dimensionless frequency of oscillation. The obtained estimates of the drag and added mass
