Abstract : The content of this paper is all about the analysis of natural frequency for avoiding resonance on the material to prevent failure and to simulate according to the boundary conditions. The Vibrations of an aircraft wing structure is analyzed using CATIA and ANSYS software. The natural frequency of the component is analyzed by the frequency at which a system vibrates about an altitude and a time period, when not subjected to a continuous or repeated external force. A wing structure is the main machine component of the aircraft which is connected to the fuselage and it is acts like a cantilever beam in which the one end of the wing is fixed and other end remains free at the end. The wing structure consists of spars, stingers, rear ribs, mid ribs and skin. In pre-stress condition, the pressure force is acting on the wing structure while flying in the sky, the overall deformation of the wing structure is calculated using a ANSYS workbench. By analyzing the frequency of the wing structure its helps to calculate resonance that should not be equal to or more than the natural frequency. The material used for aircraft wing is aluminum alloy which is less in weight and having density, one third of the steel that does not affects its strength.
