MEEN 351 Objectives and Outcomes

The objectives of MEEN 3551 are to develop in mechanical engineering students the knowledge and skills required to

1. apply the principles of computational geometry, computer graphics, design optimization, geometric-dimensioning and tolerancing, generative machining, and finite element analysis to the design of mechanical parts and systems [PEO2].

2. use modern computer-aided design tools to produce accurate computer models of mechanical parts and assemblies [PEO1, PEO2, PEO3].

3. subject computer models of mechanical parts and systems to stress analysis, thermal analysis, kinematic analysis and generative machining applications provided by modern computer-aided design systems [PEO1, PEO2, PEO3].

1. Students will be able to embed the algorithm of a parametric curve (such as a Bezier curve) into Mathcad and plot the first letter of their name using a string of at least three curves [PO01].

2. Students will be able to embed geometric transformation matrices, including rotation, translation, scaling and reflection, into Mathcad to transform a 2D or 3D object [PO01].

3. Students will be able to establish an objective function and compute the optimum value of a geometric parameter (such as a diameter) for a simple mechanics of materials problem with one or more constraints [PO01, PO03, PO10].

4. Students will be able to identify, label or list common geometric symbols used in geometric dimensioning and tolerancing [PO03, PO10].

5. Students will be able to compute the unknown displacements, forces, and stresses in 2D truss members using the direct stiffness formulation of the finite element method [PO10].

6. Students will be draw 3D parts with specified dimensions by extrusion, revolution, sweeping, or lofting of 2D cross sections or by constructing the bodies out of simple geometric primitives (cubes, spheres, cones, cylinders, . . .) [PO03, PO10].

7. Students will be able to employ geometric constraints (colinearity, perpendicularity, etc.) in the process of drawing parts [PO03, PO10].

8. Students will be able to create and modify the parameters of a 3D part [PO03, PO10].

9. Students will be able to create assemblies of parts and animate the motion of these assemblies [PO03, PO10].

10. Students will be able to generate tool paths for drilling and three-axis milling operations required to produce parts having simple cavities, pads and bosses [PO03, PO10].

11. Students will be able to determine the stresses and displacements of 3D parts subjected to simple boundary conditions (fixed displacements with point or pressure loadings) [PO03, PO10].

12. Students will be able to use the I-DEAS tutorials to learn the how to use the software on their own (such as for thermal analysis) [PO03, PO04, PO08, PO10].
