Full textThe system identification methods of mechanical structures in operational conditions are today very attractive. They allow to estimate the modal parameters using output-only data from sensors localized on the structures. In this research we propose two identification methods of vibrating systems, without knowledge of the excitation. These methods are the subspace methods and wavelet transform method. The modal analysis, by subspace methods, is based on the estimation of state matrix of the vibrating system. In this work we propose three methods to estimate this state matrix exploiting the special structure of a matrix obtained from the data. We determine weighting matrices which allow to identify modes poorly excited. As the model order is unknown, we progressively increase this order and we establish stabilization diagrams. Several criteria are also proposed in order to suppress the spurious modes. The wavelets are signals used to analyze other signals. With the time-frequency representation obtained from the wavelet transform we can follow temporal and frequential evolution of each component, which is not the case with the use of Fourier transform. In this work, we use the wavelet transform to identify vibrating linear systems from transient responses. The procedure is then extended to free responses of nonlinear mechanical systems in order to characterize non-linearities and identify its parameters

Full textThe work developed in this phd-thesis is focused on the treatment of the uncertainties of the parameters of a vibro-acoustical system. After several recalls of numerical techniques to treat the impact of the randomness of these parameters on the behaviour of the system, we initiated an analytical method by using on one hand classical calculations of probability and on the other hand the modal analysis. So we began by writing the analytical expression of the probability density function of the frequency response of a harmonic oscillator by considering at first that only the natural frequency is random and governed by an uniform law, then in a second time that only viscous damping was random (of uniform law too). In a third time we considered the couple as being random. By using this last resolution allowed us to superpose n oscillators and to write the probability density funstion of a vibrating system of n degrees of freedom: we called this method the probabilistic modal analysis. We introduce an application on the Euler-Bernoulli beam treated by finite elements method. In this thesis, we introduce numerical techniques about the treatment of the randomness upon parameters (projection on the polynomial chaos), but a step towards the identification of parameters and their randomness was also tried. In this frame, first we use methods of nonparametric identification, then we display a family of methods based on the envelopes of the frequency response of the system given by the analytical resolution

Full textThis study proposes a general formalism which permits the inclusion of the diverse methods of modal synthesis. Thus, the analysis of the symetry between the primal and dual formulations led to new procedures. Furthermore, the introduction of integral operators allowed the analysis of their efficiency. The definition of a new family of modes allows the identification of modal models based on simple vibratory tests. Optimal control of boundary characteristics led to the definition of highly efficient models despite the low number of degrees of freedom utilised. The behavior laws of the materials and of the interfaces are presented in such a way as to derive simplifying hypotheses which allow the modal synthesis methods to be extended to visco-elastic and non-linear modes. In particular, the utilisation of complex and non-linear modes is justified. The latter are linked to the normal transformation and their stability is studied through the use of the Poincaré transformation. Several methods for identifying models from dynamic trials are stated. New experimental and numerical procedures are proposed in the case of strong damping and of non-linearities localized on the interfaces. Throughout the study many numerical and experimental results are utilised to illustrate the diverse developments and to verity the efficiency of the diverse methods of modal synthesis

Full textDifferent experimental modal analysis methods based on laser interferometry measurements (espi) are presented. The main advantage of these techniques is to provide high spatial resolution vibration information recorded simultaneously and contact-free. A first hybrid approach acts as a complement of a classical analysis using sensors with espi records. Under specific assumptions, mode shapes are directly estimated from operational responses measured by the optical system. A second method is presented combining modal appropriation techniques and espi measurements. This approach allows to obtain normal modes of the structure associated conservative system, even in case of modal coupling. Finally, a method based on measurement of transfer functions by optical way is then presented. Modal identification is performed using spatial domain data condensation technique and allows to obtain complex poles of the concerned dissipative system. These different approaches have been validated using simulated and experimental test cases and applied on automotive body panels. The use of these methods is especially well adapted in the view of validation and updating of structural finite elements models
