Course detail

Machine Design - Mechanisms, 3D Print and Solidworks

FSI-6KMAcad. year: 2020/2021

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.

This course is compulsory-optional in 3rd year of general bachelor's degree program. Its choice is recommended for all students who are oriented towards solving of various mechanical design problems and who are considering branches like M-ADI, M-AIR, M-ENI, M-KSI, M-FIN, M-MET, M-PRI, or M-VSR for their master study program.

Learning outcomes of the course unit

- Knowledge of the principle, construction and use of basic types of drive mechanisms and machines.
- Ability to use acquired knowledge creatively to design new machines and equipment.
- Significant extension and improvement of previous mechanical design courses.
- Skills in 3D printing of plastic parts and their dimensioning for Fused deposition modeling technology. Practical experience in 3D modeling of mechanical parts that will be verified on 3D printed mechanisms.
- Ability to work with parametric models and efficient design and process of various design solutions. Application of this experiences during construction work, creation of virtual models in semestral projects, diploma and bachelor theses and implementation of prototypes.
- Practical experience with 3D printing, as a fast growing area, expands a competitiveness in the labor market.

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.

Aims

Graduates will be able to design and model parts and assemblies in CAD software Solidworks with respect to production using 3D printing. At the same time, they will gain an overview of modern mechanisms and drive machines and their practical use.

Specification of controlled education, way of implementation and compensation for absences

Attendance at lectures is recommended; attendance at practicals and laboratory practicals is obligatory and checked by the lecturer. Compensation of missed lessons depends on the instructions of course supervisor.
