Abstract:

This project is all about the analysis on the vibrational characteristic of a fuselage structure of an unmanned ariel vehicle (UAV). Aluminium materials are used in all structural componenets.The vibrational characteristic will be analysed using the modal analysis in Ansys and the modal characteristic of the fuselage structure is determined for free and forced configuration. Thus we can find out the natural frequency and dynamic stresses on the designed fuselage. Also we can find out the the total deformation and equivalent stress using stress analysis. Thus by the modal analysis of this structure, results can be produced for varying inputs.


Keywords Aluminium, Natural frequency, Dynamic stresses, Ansys, CATIA V5 R20.
