| 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 |
