This semester, we started the course "introduction to vibrations", in which we learned that every particle on earth vibrates in its own natural frequency where no loads are applied. That's what we call free vibration.
However, this homework is about the use of finite element method analysis to predict the behavior of a thin plate and project it on a rectangular wing of an airplane. For this purpose, I personally used the catia v5 generative structural analysis tool respecting the guidelines and design criteria of the plate.
[...] We run the macro and then we get the plotting in catia. starting from 0 to 400, we can get two airfoils apart from 400 mm. So, here's the final design applying the material characteristics: and finally, I designed an empty engine to assemble in the wing. Final Design ( approximate due to limited tools in catia) Design of the Plate Design of the wing To conclude, as the results show, while adding the empty cylinder, the mass will affect the stiffness of the whole component.

[...] That's what we call free vibration. However, this homework is about the use of finite element method analysis to predict the behavior of a thin plate and project it on a rectangular wing of an airplane. For this purpose, personally I used the catia v5 generative structural analysis tool respecting the guidelines and design criteria of the plate. According to this, I chose 10 natural frequencies (f1,f ,f10) for fun, so the plan of this homework is as it follows firstly, I will show all the steps of the drawing, setting up the structural analysis mode, and modifying the material characteristics. [...]
[...] After the calculations finish, we click on Image>Deformation and then it shows the first natural frequency vibration mode. For different modes, we can select "Contraintes de Von Mises". Design for the wing Step We open CATIA V5, we go and click in "Démarrer">Shape> and we select the yz plan. For the wing, we should design an airfoil. My preference, I selected the NACA 2412 symmetric airfoil because maybe as an intuition from me it will have something special from cambered airfoils. [...]
