Identification of flutter derivatives by forced vibration tests

Blog Article

Results of an experimental study related to flutter phenomenon are Skirt presented in the paper.Two cross-sections are considered: a rectangular cross-section and a typical symmetric bridge cross-section.Stationary coefficients and instationary flutter derivatives are determined by means of forced vibration tests.

The identification technique is presented in detail.Pressure measurements at the centre of the bridge cross-section are also performed.Main wind flow patterns are analysed Oxygen Conservers based on pressure distribution data.
