Theoretical-Experimental Method for Determining the Parameters of Damping Based on the Study of Damped Flexural Vibrations of Test Specimens 2. Aerodynamic Component of Damping

Abstract

The aerodynamic component of damping of a vibrating plate in the range of parameters characteristic of damped flexural vibrations of test specimens is investigated. On the basis of a large series of numerical simulations in the dynamics of two-dimensional flow of gas around a plate, we managed to suggest a unified approximating equation for the damping constant in terms of dimensionless parameters of the process considered. © 2014 Springer Science+Business Media New York.
