Project objective

Research objectives and content Study's aim: Aim of the research is to develop and apply to real engineering structures a new technique for system identification in mechanical and civil engineering. The research will be concerned with the definition and the application of a new technique, based on the use of higher order spectra, for parameter estimation of non-linear mechanical and civil structures subjected to environmental loads, such as wind and ocean wave forces. The innovative nature of the project itconsist of the novel use of higher order spectra for real engineering problems. In particular, I will analyse the dynamical behaviour of offshore structures to ocean wave forces. The work plane will involve computational work. with the development of data analysis software, and experimental work, with the measurement of the roll angle of a single degree of freedom oscillator subjected to random waves simulating the real sea action. The experimental work will be developed in the laboratory of the School of Engineering at the University of Sussex by using existing experimental equipment. Training content (objective, benefit and expected impact) Objective of the request grant is to demonstrate the applicability of higher order spectra based identification techniques to a wide variety of mechanical and civil engineering problems The requested training grant will permit the applicant to further his understanding of the use of higher order spectra in structural identif cation and to apply this technique to real engineering problems. The expected impact will be that higher order spectra based techniques will be brought to the attention of the industrial and accademic world. Links with industry / industrial relevance (22) The research subject is particulary concerned with future civil and mechanical engineering industrial applications. The research results can be used for developing software or machinery for dynamical systems identification.
