Course detail

Machine Design - Mechanisms, 3D Print and Solidworks

FSI-6KM-AAcad. year: 2018/2019

During the lectures, we familiarize ourselves with mechanisms and drives of the contemporary machines. We will analyze their principles, describe their design and application. The most common kinematic and hydraulic mechanisms will be introduced as well as an electric and internal combustion engines. Attention is also paid to the microelectromechanical systems and renewable energy engines. We will discuss the application of mechanisms in various engineering branches. For example, you will learn about powerful engines for motorsport, design of high-speed cams, unconventional transmission design or about applications of universal-joint shafts.
During the exercises, we will learn about modeling in parametric modeler Solidworks and practically try out the design and building of small mechanisms using 3D printing.

Learning outcomes of the course unit

You gain knowledge of the principle, construction and use of basic types of drive mechanisms and machines. Gain ability to use acquired knowledge creatively to design new machines and equipment. Your knowledge gained in previous mechanical design courses will be significantly extended and improved. You get the necessary skills in 3D printing of plastic parts and their dimensioning for technology Fused deposition modeling. You also get practical experience in 3D modeling of mechanical parts that you verify on 3D printed mechanisms. With knowledge of parametric models you will be able to efficiently design and process various design solutions. Gained experience you apply during construction work, creation of virtual models in semester projects, diploma and bachelor theses and implementation of prototypes. Practical experience with 3D printing, as a fast growing area, expand your competitiveness in the labor market.

Prerequisites

Knowledge of kinematics (kinematic analysis of mechanisms), dynamics (multibody dynamics, balancing), machine design (fasteners, gears, clutches, flywheels) at the level of the Bachelor's degree programme aimed on mechanical engineering.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Practicals are focused on 3D printing processes and software tools for engineering. Practicals are supplemented by work in the laboratory.

Assesment methods and criteria linked to learning outcomes

Graded credit course requirement is elaboration of semestral project: Semestral projects will be addressed in teams of 3-5 students. Projects will focus on the creation of virtual and functional model of specified mechanism. Evaluation will consider SolidWorks 3D model and a physical model manufactured on 3D printer.
