Two mathematical models for describing the effective stiffness and the equivalent viscous damping ratio of wire rope springs, as amplitude dependent, were developed. Twenty-four springs were tested in free vibration and the displacement decays were recorded. The free vibration time history was used to calculate the effective stiffness and the equivalent viscous damping ratio. For each displacement...
For time-domain flutter analysis, the frequency-dependent self-excited forces acting on the structure can be approximated in the Laplace domain by Rational Functions. The existing Rational Function Approximation (RFA) approach involves approximation of the experimentally obtained flutter derivatives. This motivated the formulation of a system identification technique (Experimental Extraction of Rational...
