In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

marine industry requires continued development of new technologies in order to produce oil. an essential requirement in design is to be able to compare experimental data from prototype structures with predicted information from a corresponding analytical finite element model. in this study, structural model updating may be defined as the fit of an existing analytical model in the light of measu...

In this paper, we continue our paper [7] to develop an efficient numerical algorithm for the finite element model updating of quadratic eigenvalue problems (QEPs). This model updating of QEPs is proposed to incorporate the measured model data into the finite element model to produce an adjusted finite element model on the mass, damping and stiffness that closely match the experimental modal dat...

Finite element model updating of a structure made linear elastic materials is based on the solution minimization problem. The goal to find some unknown parameters finite (elastic moduli, mass densities, constraints and boundary conditions) that minimize an objective function which evaluates discrepancy between experimental numerical dynamic properties. depends nonlinearly may have multiple loca...

At the time of designing structures up to date, density and magnitude load have increased, requirements for regulation also become more stringent. To ensure essential requirements, especially mechanical resistance stability, numerical modelling structure is carried out according current regulations. Due various assumptions, idealization, discretization, parameterizations that are introduced mod...
