Vibro-acoustic analysis of a domestic product based on experimental measurement and hybrid modelling (2021)
Journal Article
Meggitt, J., Banwell, G., Elliott, A., Moorhouse, A., & Langley, R. (2021). Vibro-acoustic analysis of a domestic product based on experimental measurement and hybrid modelling. Applied Acoustics, 182, 108144. https://doi.org/10.1016/j.apacoust.2021.108144

The purpose of this paper is to present a case study whereby a hybrid experimental-numerical model is used to analyse the structureborne
radiation from a domestic product (vacuum cleaner head). The passive (including radiative) properties of the str... Read More about Vibro-acoustic analysis of a domestic product based on experimental measurement and hybrid modelling.

Component replacement TPA : a transmissibility-based structural modification method for in-situ transfer path analysis (2021)
Journal Article
Meggitt, J., Elliott, A., Moorhouse, A., Jalibert, A., & Franks, G. (2021). Component replacement TPA : a transmissibility-based structural modification method for in-situ transfer path analysis. Journal of Sound and Vibration, 499, 115991. https://doi.org/10.1016/j.jsv.2021.115991

In-situ Transfer Path Analysis is a diagnostic method used to analyse the propagation of noise and vibration through
complex built-up structures. Its defining feature is the invariant characterisation of an assembly’s active components
(i.e. vibrat... Read More about Component replacement TPA : a transmissibility-based structural modification method for in-situ transfer path analysis.

Finite element model updating using in-situ experimental data (2020)
Journal Article
Meggitt, J., & Moorhouse, A. (2020). Finite element model updating using in-situ experimental data. Journal of Sound and Vibration, 489, 115675. https://doi.org/10.1016/j.jsv.2020.115675

Conventional model updating methods are based on frequency response functions (FRFs) and/or modal parameters
estimates obtained from freely suspended, or sometimes rigidly constrained, sub-structures. These idealised boundary
conditions are however... Read More about Finite element model updating using in-situ experimental data.

A covariance based framework for the propagation of correlated uncertainty in frequency based dynamic sub-structuring (2019)
Journal Article
Meggitt, J., & Moorhouse, A. (2020). A covariance based framework for the propagation of correlated uncertainty in frequency based dynamic sub-structuring. Mechanical Systems and Signal Processing, 136, 106505. https://doi.org/10.1016/j.ymssp.2019.106505

Dynamic sub-structuring (DS) is the procedure by which the passive properties (i.e. frequency response functions)
of an assembled structure are predicted from those of its constituent sub-structures. In this paper we are concerned
with the propagat... Read More about A covariance based framework for the propagation of correlated uncertainty in frequency based dynamic sub-structuring.

Evaluation of uncertainties in classical and component (blocked force) transfer path analysis (TPA) (2019)
Journal Article
Moorhouse, A., Meggitt, J., & Elliott, A. (2019). Evaluation of uncertainties in classical and component (blocked force) transfer path analysis (TPA). SAE Technical Papers, 1(4), 1779-1789. https://doi.org/10.4271/2019-01-1544

Transfer path analysis (TPA) has become a widely used diagnostic technique in the automotive and other sectors. In classic TPA, a two-stage measurement is conducted including operational and frequency response function (FRF) phases from which the con...

Development of a hybrid FE-SEA-experimental model (2019)
Journal Article
Clot, A., Meggitt, J., Langley, R., Elliott, A., & Moorhouse, A. (2019). Development of a hybrid FE-SEA-experimental model. Journal of Sound and Vibration, 452(Jul 19), 112-131. https://doi.org/10.1016/j.jsv.2019.03.027

The vibro-acoustic response of complex structures with uncertain properties is a problem of great concern for modern industries. In recent years, much research has been devoted to the prediction of this response in the mid-frequency range where, beca... Read More about Development of a hybrid FE-SEA-experimental model.

In situ determination of dynamic stiffness for resilient elements (2015)
Journal Article
Meggitt, J., Elliott, A., Moorhouse, A., & Lai, K. (2016). In situ determination of dynamic stiffness for resilient elements. Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 230(6), 986-993. https://doi.org/10.1177/0954406215618986

An in situ method for the measurement of a resilient lements dynamic transfer stiffness is outlined and alidated. Unlike current methods, the proposed in situ approach allows for the characterisation of a resilient element whilst incorporated into an...
