In Part 1 of the study, two improved Bouc-Wen models have been proposed to
describe the hysteretic behaviour of a wire-cable vibration isolator. In th
is part, a frequency-domain parametric identification procedure is presente
d to determine the model parameters from the experimental data of the cycli
c loading test. Making use of the rate-independent nature of the hysteretic
behaviour, the measured quasi-periodic data sequences are modulated to per
iodic signals. Then the model parameters are identified from a one-stage es
timate scheme using the acquired harmonic components of the displacement an
d restoring force signals. The identification results give rise to a good r
epresentation of the experimental hysteresis loops. After performing the mo
delling, the dynamic response behaviour of a wire-cable isolation system is
evaluated with reference to the shear, the roll and the tension-compressio
n modes respectively. The frequency-response characteristics in the tension
-compression mode are found to be greatly different from those in shear and
roll modes.
