Load Updating for Finite Element Models

AIAA Journal, 2003
A method for reducing the differences between experimental testing or real-world events and their finite element counterparts is presented. In this method system identification or finite element model updating are not performed; instead, the loads on the finite element model that would create equivaient displacements or strains are identified by ...

Updating Rotor-Bearing Finite Element Models

Volume 1B: 16th Biennial Conference on Mechanical Vibration and Noise, 1997
Abstract In this paper, the possibility of updating the finite element model of a rotor-bearing system by estimating the bearing stiffness and damping coefficients from a few measured Frequency Response Functions using a Genetic Algorithm is investigated. The issues of identifiability and parameters estimation errors, computational costs

Updating large finite element models in structural dynamics

AIAA Journal, 1998
In model updating problems, one tries to find design variable values affecting the input to a numerical or analytical model, such that the model output is well correlated to some target response or experimental data. Because most proposed solution techniques are iterative or require large matrices to be inverted and multiplied, severe obstacles arise ...

Updating finite element models considering environmental impacts

SPIE Proceedings, 2016
Structures are always exposed to the surrounding environment. The environmental variability (especially fluctuation in temperature) creates noticeable variations in structural modal properties. Two major mechanisms from temperature can cause uncertainties in natural frequency and mode shape measurements: i) the changes of material properties (elastic ...

Finite element model updating using bees algorithm

Structural and Multidisciplinary Optimization, 2010
In this paper the application of bees algorithm (BA) in the finite element (FE) model updating of structures is investigated. BA is an optimization algorithm inspired by the natural foraging behavior of honeybees to find food sources. The weighted sum of the squared error between the measured and computed modal parameters is used as the objective ...

Finite element model updating with damping identification

Journal of Sound and Vibration, 2009
Abstract Most of finite element model updating techniques do not employ damping matrices and hence, cannot be used for accurate prediction of complex frequency response functions (FRFs). In this paper, damped finite element model updating procedure is proposed and tested with the objective that the damped finite element updated model is able to ...
