The folded-beam waveguide absorber (FBWA) is a beam folded back and forth over itself: when vibrated at one end, waves travel along this beam ad are absorbed by damping (either natural or deliberately added). The fact that it is folded means that in effect a very “long” beam can be folded into a “small” physical space. Properly designed, they can be extremely effective vibration absorbers.
This project will involve modelling a FBWA, performing numerical simulations, manufacturing one, then measuring its dynamics properties and comparing with the numerical results. You will undertake parameter studies to investigate the performance and how it depends on the FBWA properties (e.g. material, length, thickness, width, presence of damping material etc).
