....of the system from records of the stochastic response. Structures are often characterized by a low level of damping implying narrow band response with slow change of the energy of the system over a period. This observation formed the basis of a stiffness estimation procedure introduced by Roberts et al. 1992), where interpolation of the kinetic energies at mean level crossings is used to estimate the energies at the extremes of the position. A standard regression technique yields an estimate of the elastic potential as function of the position. Part of the problem of applying this type of estimation ....
....the regression. In this paper a non parametric iterative estimation procedure is proposed, which gradually reduces the bias. A global procedure for the estimation of damping relative to excitation intensity based on a generic expression for the probability density of the energy is proposed by Roberts et al. 1992,1994) This method relies on knowledge of the elastic potential. In the present paper a non parametric estimation technique based on the probability density of the energy at mean level crossings is proposed. The separation of damping and excitation can be obtained by estimating the absolute ....
