Development of an analytical model for the nonlinear dynamics of a highly-flexible cantilever beam prototype

Reference persons CECILIA SURACE

Description At the current state, the dynamical behaviour of slender structural elements, such as aeroplane wings, wind turbine blades or gas turbine fans, is often assumed to be linear. This hypothesis allows using linear Modal Analysis (LMA) and other widespread techniques to model the expected structural response to a time-varying input force.
Nevertheless, the actual dynamics of flexible elements is generally nonlinear, due to the large displacements caused by even small external forces. In common practice, Finite Element Modelling is widely used for the investigation of these second-order geometrical effects, yet the computational time required is far too large for online estimation.
The student will be fully involved in the definition of a closed-form analytical model for the dynamics of a cantilever beam with variable cross-section undergoing large deflections. The model will be after implemented in Matlab, compared to data from experimental results and benchmarked against numerical simulations obtained from a standard commercial software (ANSYS Mechanical APDL).
The project will be conducted in collaboration with the School of Aerospace, Transportation and Manufacturing (SATM) at Cranfield University, UK, as an offshoot of the Agile Wing Integration (AWI) consortium and it might be integrated with a short period abroad at that Institute, depending on the project’s developments and student’s wishes.
The project is estimated to last circa 5 months and will require a full-time participation from the student.
