Summary
Scanning 3D laser vibrometer for non-contact in-plane and out-of-plane vibration measurement. The requested 3D scanning laser vibrometer is intended for the characterisation of 3D vibration of small and large, simple and complex structures, for the purpose of understanding the vibratory behaviour as a precursor to optimising noise and vibration control strategies. It has application to small items for which the use of contact sensors is impossible or impractical, as well as large structures for ....Scanning 3D laser vibrometer for non-contact in-plane and out-of-plane vibration measurement. The requested 3D scanning laser vibrometer is intended for the characterisation of 3D vibration of small and large, simple and complex structures, for the purpose of understanding the vibratory behaviour as a precursor to optimising noise and vibration control strategies. It has application to small items for which the use of contact sensors is impossible or impractical, as well as large structures for which the vibration fields can be complex and a 3D scanning capability is essential. Examples include micro-positioning actuators, piezo-electric motors, live cell response, disk brakes, aircraft and vehicles. Outcomes include the enhancement of existing research projects, allowing a greater understanding of the noise and vibration phenomena.Read moreRead less

Novel quantitative sizing of inaccessible and hard-to-inspect defects to address the challenges posed by innovations in airframe design. Modern unitised aircraft structures cannot be reliably inspected using traditional techniques. This project will develop new techniques to quantify defects required for this innovation in aircraft component design. This research will improve the through-life support of future metallic and composite aircraft structures and improve air safety.

Summary
Topology optimisation for advanced engineered nanostructures. Advanced technological innovation requires extraordinary material properties, which can be generated directly from engineered nanostructures by manipulating surface plasmon resonances. The project will develop a new computational method for nanostructural design and expect to benefit aerospace, biomedical, optical and energy engineering fields.

The prediction of structure-borne noise transmission in large welded ship structures is required, in order to design maritime vessels with greater ship power and reduced weight, without increasing the noise levels. The aim of this project is to develop a hybrid approach for structural dynamic analyses using an analytical waveguide method and Statistical Energy Analysis. The theoretical estimation and associated experimental measurement of the SEA parameters (modal density, coupling and internal loss factors) form the basis for the hybrid approach. The outcomes will result in improved predictive techniques for dynamic analyses of large complex resonant structures.Read moreRead less
