Course detail

Machine Design - Mechanisms

FSI-6KMAcad. year: 2013/2014

The aim of the course is to provide an overview of the mechanisms and basic types of driving machines used in current machines and equipment. Particularly the principle, construction and use of such mechanisms are discussed. The most common kinematic mechanisms and hydraulic, electric and combustion engines are discussed as well. Attention is also paid to microelectromechanical systems and engines fueled with renewable energy sources.

Learning outcomes of the course unit

Knowledge of the principles of operation, design and application of the basic mechanisms types and the driving machines. Ability to apply gained knowledge to the design process of new machinery and equipment in creative way.

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. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Graded credit course requirements:
A) Elaborated semestral projects: The minimum number of points needed for the acceptance of semestral projects is 30 from 60 possible. Points can be obtained based on the following criteria:
1. Student activity in tutorials. Teachers discuss solutions with students through tutorials to obtain an overview of the student's work during the semester.
2. Elaboration and submission of semestral projects on schedule set by the teacher. The complete project consists of calculation report created in Mathcad software, including assignment, input parameters, figures and graphs.
3. The defense of semestral projects through discussion with the teacher, where the student must demonstrate his knowledge about topic. If the student does not fulfill the requirements for the semestral project acceptance, he is entitled to have a maximum of one additional project defense. The date of defense is set by the teacher, usually during the examination period.
B) Passing multiple-choice test: minimum score for passing the test is 20 out of 40 possible points. Multiple-choice test is performed on the computer and it utilizes the examination system of the Institute of Mechanical and Industrial Design. The test topics cover the problems mentioned in lectures and tutorials. The test is composed of theoretical and computational questions. Each question has five answers, of which only one is correct. An incorrect answer does not mean negative point. A student card, pen and calculator are demanded to access the test room. Use of any literature during the test is not allowed. If the student does not fulfill the requirements for passing the test, he is entitled to have a maximum of one retake test. The date is specified by the teacher, usually during the examination period. The retake test is counted as successful at 50 % score and above.
The final score of the whole course consists of the total number of points earned from semestral project and multiple-choice test. The minimum required score is 50 points out of the maximum 100 points. The final score determines the grade according to ECTS.

Attention is also paid to microelectromechanical systems and engines fueled with renewable energy sources.

This course is compulsory-optional in 3rd year of general bachelor's degree programme. Its choice is recommended for all students who are oriented at mechanical design and solving of various design problems in branches such as M-KSI, M-ADI and others.

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

Attendance at lectures is recommended, attendance at seminars is required - a maximum of two excused absences per semester are tolerated. Lectures provided by team of teachers of the Institute of Machine and Industrial Design are available as the electronic previews in the Moodle system. The tutorials take the form of semestral projects and praktical laboratory exercises. It is possible to use both private notebooks and computers in the classroom (WiFi available) during tutorials. The Mathcad software is recommended for elaboration of semestral projects.
