Data variability and parameter uncertainty in composite shaft structural vibration measurement and numerical model updating

Cel

The main goal of this project is to investigate the dynamic properties of fibre reinforced shaft. A combination of non-destructive experimental and numerical simulation methods will be employed. The test results will be used in two ways: to derive knowledge of mechanical properties of a structure and to update the non-deterministic Finite Element model according to values obtained from test. In the experimental part the variability of physical properties will be taken into account. Model updating will include uncertainties of its parameters by means of interval, stochastic and fuzzy methods.

An optimisation technique for both test (sensor number and location) and numerical (model reduction) parts will be applied. Such a combination demands to take advantage of knowledge from several fields: free vibrations, composite materials, measurement methods (especially experimental modal analysis), variability in measurement data, uncertainties in model parameters, signal processing, finite element method modelling, model updating, optimisation, statistics. As a result of this project set of updated numerical models will be developed with an introduction of quality function assessing the influence of particular factors on model reliability related to overall workload demanded. Also a set of variable test data will be assessed with a criterion of its application in industrial cases like diagnostics, Structure Health Monitoring.
