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.

Robust NVH engineering using experimental methods - source characterization techniques for component Transfer Path Analysis and Virtual Acoustic Prototyping (2019)
Journal Article
Wienen, K., Sturm, M., Moorhouse, A., & Meggitt, J. (2019). Robust NVH engineering using experimental methods - source characterization techniques for component Transfer Path Analysis and Virtual Acoustic Prototyping. SAE Technical Papers, 1(4), 1766-1778. https://doi.org/10.4271/2019-01-1542

A major challenge in automotive NVH engineering is to approach complex structure-borne sound and vibration problems with sufficient accuracy but reasonable experimental effort. Typical issues encountered are poor correlation between objective compone...

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.

A covariance based framework for the propagation of uncertainty through inverse problems with an application to force identification (2019)
Journal Article
Meggitt, J., Moorhouse, A., & Elliott, A. (2019). A covariance based framework for the propagation of uncertainty through inverse problems with an application to force identification. Mechanical Systems and Signal Processing, 124, 275-297. https://doi.org/10.1016/j.ymssp.2018.11.038

Inverse problems are widely encountered in fields as diverse as physics, geophysics, engineering and finance. In the present paper, a covariance based framework for the estimation of their uncertainty is presented and applied to the problem of inve...
