Course detail
Machine Design - Mechanisms, 3D Print and Solidworks
FSI-6KM Acad. year: 2022/2023 Summer semester
During the lectures, students will learn about the mechanisms and drives of contemporary machines, their principles, design and use. The most commonly used kinematic and hydraulic mechanisms and electric and internal combustion engines will be introduced. Attention is also paid to microelectromechanical systems and motors powered by renewable energy sources. Applications of mechanisms in practice will also be discussed, for example, students will learn about high-performance drives for motorsport, design of high-speed cams, design of unconventional gears, and applications of articulated shafts.
During the exercises, students will learn the basics of Solidworks modelling through team projects, and they will get hands-on experience with 3D printing technology in the design and construction of mechanisms and their production 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.

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 Filament Fabrication 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.
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.
Planned learning activities and teaching methods
Lectures, seminars, laboratories.
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. The overall evaluation includes a separately modelled part in Solidworks and then the completion of the mechanism project (model in Solidworks and the manufactured mechanism on a 3D printer) and its presentation.
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 seminars and laboratory seminars is mandatory and controlled by the teacher. It is necessary for each student to have their own laptop during the exercises. Compensation for missed classes is the responsibility of the exercise leader.
