A discussion about finite element analysis of aircraft wing structure
One of the most significant components of aircraft design is the wing,the wings are the main lifting surfaces that support the airplane in flight.The structures of wings must have enough strength and rigidity to ensure the safe of the aircraft.Usually,the displacements of the structures are calculated by using finite element method.But it is very difficult to select a reasonable finite element model to approximate the actual structure.In this study,two models are adopted to calculate the displacements of the wing structure.The first is a model of rod and shear plate,the second is a model of beam and shell.The disadvantages and advantages of two models are discussed.As seen from the comparison with the test date,two models proposed are both feasible to analyze the wing structure.
