Identification of flutter derivatives by forced vibration tests

Blog Article

Results of an opheliasmuse.com experimental study related to flutter phenomenon are 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 skull bride and groom 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 based on pressure distribution data.
