Mechanical Engineering

This course provides the basic insights into the use of advanced computer aided tools for 3D product modelling. From a product idea a computerized model is made (product modelling) of a physical object by surface modeling, 3D scanning, and printing. Product simulation gives an insight to the use of real time simulation (Virtual Reality, VR). The created product models give possibilities to simulate the relations between man, product, and environment. The course includes parts of 3D product modelling by surface modelling, scanning, product simulation, modelling and Rapid Prototyping in 3D. The computerized surface modelling (Rhino och Maxwell studio) deals with the following areas: introduction to 3D modelling; interface basics, primitive objects (spheres, cubes, cylinders); transformation, mirror, and duplicate objects; NURBS-curves (CVs, Edit points and Key-points curves); turn curves into different types of NURBS surfaces (skinned, revolved, planar, extruded and swept); edit CV-curves; working with layers and use layer symmetry; trim excess of surfaces; create advanced double bent surfaces. Other areas covered in the course are create STL (Sterio Lithography) file; export model to CAD-program; rendering basics using different types of renders including light setup, shaders and textures; animation basics. The computerized product simulation deals with the following areas: introduction to Virtual Reality; interface basics; importing 3D objects; associate behaviors with the objects; create interactivity; the 3D scanning part includes some basic 3D scanning methods; scanning objects and exporting the data to a computer program. The rapid prototyping part of the course includes creating a 3D print from a computerized product model to a physical object. Assumed prior knowledge: MMK010/MMKA15 Manual and Computer Aided drafting in Mechanical Engineering.

The course examines the motions of linkages, gear sets, and cams. Students learn about the analysis of displacement, velocity, and acceleration of mechanisms by using graphical and analytical methods. The course analyzes real-world engineering applications of the mechanisms. It covers the kinematic analysis by using Autodesk Inventor. 

This course provides a fundamental knowledge of dynamics, including kinematics and kinetics of particle, system of particles, and rigid bodies in planar and three-dimensional motion. A systematic approach, namely Vector Analysis and Modeling Procedure (VAMP), is introduced to precisely describe linear and angular positions, velocities, accelerations, forces, and torques for generating a set of equations of motion, without missing any terms. Other modeling of work/energy equations, impulse/momentum equations, impact of particles and rigid bodies, and Euler equations are also addressed. Not only are students trained to have the ability of modeling dynamic systems in terms of equations of motion, but they are also experienced with engineering insight of physical laws.
