Accurate estimation of the non-parametric FRF of lightly-damped mechanical systems using arbitrary excitations KU Leuven
© 2019 Elsevier Ltd Lightly-damped mechanical systems exhibit strong resonant behaviour which could potentially result in life-threatening situations. To prevent these situations from happening, frequency response function measurements are essential to accurately characterise the resonant modes of the mechanical system. Unfortunately, these measurements are distorted by leakage and (long)transient phenomena. Local modelling techniques have been ...
