Повний текст джерелаNoise and vibration are important topics in the automotive industry for several reasons, including passenger comfort and structural integrity. The main objective of this thesis is to propose a series of appropriate methods to optimize structural system characteristics, so that the vibration and noise can be reduced. To achieve this goal, interface control strategies are employed, including bonding viscoelastic layers onto the most heavily deformed zones and introducing frictional damping devices calibrated on certain resonance frequencies. Such built-up structural systems are numerically investigated via a generalized modal synthesis approach that incorporates several groups of modes. The employed modal synthesis approach consists of several levels of condensation. The first one is on the internal degrees of freedoms (DOFs) of each substructure, and the second condensation is on the branch modes so as to reduce the boundary DOFs among substructures. For coupled fluid-structural systems, a third condensation on the fluid DOFs is suggested. With these condensation techniques, the system dimension can be significantly reduced. The method allows us to obtain the forced response of the structures as well as the pressure variation of the fluids. Additionally, modal parameters characterizing vibration and noise transmission paths can be deduced as mid-stage results. We show that these modal parameters can be used as optimization objective during the interface configuration design. The Pareto front of the optimal design is achieved by employing Kriging approximations followed with an elitist multi-objective genetic algorithm. Another advantage of the modal approach is that a modal overview on the system characteristics is provided by analyzing the natural frequencies, modal damping ratios and the aforementioned modal parameters. The modal synthesis approach is further extended to study nonlinear systems. The basic assumption is that the nonlinear modes are weakly coupled. Nonlinear modal parameters, such as modal frequency and modal damping ratio, contain the essential nonlinear information and depend on modal amplitude. The main idea is to compute nonlinear normal modes according to their modal amplitude and superimpose the response of several nonlinear modes to obtain the overall forced response. The method is applied to systems involving Duffing and dry friction nonlinearities. In the case of dry friction, a generalized Masing model is considered to capture the dry friction nature. Both complex modes and real modes are used in the modal synthesis, leading to different frictional damping terms. We show that the nonlinear modal synthesis combined with the generalized Masing model yields a simple, fast and efficient numerical method to describe nonlinear performance of structures with dry friction

Повний текст джерелаThe increase of large ships dimensions shifts their structural natural frequencies towards common wave frequencies, inducing more interactions between the classic seakeeping response and the structural response. Accurate modeling of wavestructure interactions becomes a key issue for architects and classification societies during the design of a ship. In this respect, a new numerical tool for fluidstructure interaction is developed, combining a finite difference RANSE description of the fluid domain with ICARE-SWENSE and an analytic beam model, within a modal approach. Thanks to the use of a simple formulation for the structure part, the tool inherits ICARE-SWENSE tolerance properties with regard to large time steps, while still taking into account hydrodynamic nonlinear effects. Results presented for a flexible barge in diffraction and radiation according to flexible modes validate the first steps of the coupling procedure. Special consideration is given to hydrodynamic non linearities threshold and their impact on the structural response. A first implementation is shown for the resolution of the equation of motion for the elastic degrees of freedom. Parametric studies on ship resistance in both regular and bichromatic waves are included as a stepping stone towards future simulations of ship hydroelasticity in irregular waves

The dynamics of nonlinear coupling mode-locked semiconductor lasers is n umerically simulated using a two-dimensional time-domain beam propagationmet hod (BPM). In an appropriately designed ring cavity, a pulse can be comp ressed from a few hundred picoseconds to a few picoseconds as a resultof li near coupling and nonlinear gain saturation in the semiconductor optical amplifier (SOA). Passive mode-locked semiconductor (GaAs/AlGaAs)lasers ba sed on either nonlinear directional coupling or nonlinear multimodeinterferenc e (MMI) coupling are numerically investigated. The performance of this pa ssive mode-locked semiconductor laser is evaluated by varying parameters s uch as the input seed pulse energy, pulse width, unsaturated gain in the SO A, and the cavity setup. It turns out that the lasers with MMIcoupler reveal better fabrication tolerance in the lateral direction and shorter coupler l ength than those with conventional directional coupler.

In this thesis, we report our research results of semiconductor laser mode-l ocking based on nonlinear coupling in a multi-mode interference waveguide.Such a phenomenon is similar to the nonlinear coupling in a directional coupler. The amplifier waveguides were fabricated with a GaAs/AlGaAs multiplequantum we ll epitaxial structure. With a linear external cavity of 30-60cm cavity lengt h the laser system produced pulse trains near 840 nm with a repetition rate of 250-500 MHz. The mode-locking could be switched on from the cw mode by incre asing the injection current. Typically, the threshold for cw operation was ar ound 90 mA and the turn-on of mode-locking was around 110 mA. The spectral wi dth of the mode-locked output was about 3 nm, implying that the output pulse c an be as short as several hundred femtosecond if appropriate dispersion compen sation can be arranged.
