Course objectives

The aim of the course Machine elements I is to familiarise students with the type of machine elements and design of them.

Course content
Lectures

Categorization of machine elements. Basics of technical calculations and product design. Static and dynamic dimensioning and analysis of machine elements. Dimensioning of screw joints and calculation of torques at threads. Design of sliding and rolling bearings, selection and verification of them. Design, calculation and verification of axes. Force and form locking joints. Theory and design of welded, soldered and glued joints. Design and calculation of frame structures.

Seminars

Introduction to the basics of modern computer-aided mechanical design, including modeling and assembling parametric components, and creating technical drawings of all of these.

Labs

Introduction to the basics of modern computer-aided mechanical design, including modeling and assembling parametric components, and creating technical drawings of all of these.

Acquired competences
Knowledge

1. be able to interpret, characterise and model the design and operation of the structural units and elements of mechanical systems, the design and interconnection of the systems used, 2. be able to apply the principles and methods of calculation and modelling in mechanical engineering design, 3. be able to construct simple mechanical models (with the necessary abstractions and neglections), 4. be able to carry out geometric and basic strength design of simple sliding and rolling bearings, 5. be able to determine the service life of rolling bearing arrangements, select the lubricant required, choose the appropriate bearing for a simple design, 6. be able to select, size and check joints (including shaft joints) and fasteners of the most important materials, forces and shapes, 7. be able to check the strength of shafts, select design dimensions for static loading 8. be able to independently study literature (including Internet sources), use catalogues and design aids, 9. using the above (and incorporating knowledge from other subjects), be able to carry out simple design tasks, including documentation and interpretation of technical drawings.

Skills

1. know the most elementary methods and procedures of mechanical engineering and design methodology, 2. be familiar with the phenomenon of fatigue, the principles of design for repetitive loading, the main methods of traditional (safety factor based) and new design procedures, the main principles of design and checking of machinery structures, 3. be familiar with the main types of joints and fasteners, their principle of operation, their forces, selection, sizing and checking methods, 4. know the main characteristics and operating principles of the various types of plain and roller bearings, 5. know the typical failure modes of plain and roller bearings, their causes and the countermeasures to avoid them, 6. be familiar with the design, sizing and inspection methods of welded frame structures, including fatigue and deflection testing

Attitude

1. collaborate with the instructor and fellow students in the development of knowledge, 2. expands his/her knowledge through continuous learning, 3. is open to the use of information technology tools, 4. strives to solve problems accurately and without errors.

Autonomy and responsibilities

1. independently think through design problems and/or problems to be solved for simple mechanical structures and solve them on the basis of given sources, integrating and using knowledge acquired previously or in parallel in other subjects, 2. is open to reasoned critical comments, 3. applies a systematic and complex approach (taking into account as many aspects as possible) in his/her thinking, 4. carries out his/her work with the responsibility and conscientiousness of a (future) engineer.

Additional professional competences

The student will become familiar with the basic facts, interrelationships, limits and boundaries of the knowledge and activity system of the field of design, calculations and verification of machine elements. He/she is able to apply the acquired technical scientific principles, rules, contexts and procedures in solving routine tasks in the field of mechanical engineering. Ability to understand and process technical documentation. Open to general and specific knowledge underpinning the technical discipline. Is able to evaluate realistically the results of his/her own work.

Requirements, evaluation and grading
Mid-term study requirements

During the semester, there are two mid-term performance appraisals, which can be corrected or made up once. A satisfactory results in both of appraisals are a prerequisite for obtaining a satisfactory mid- term grade.

Exam requirements

Generative AI usage

1st position: The use of GAI tools is not permitted when solving tasks. This means that GAI tools cannot be used when creating or solving formative or summative assessment elements, and the use of generative AI constitutes academic misconduct. The use of AI tools for language and spelling checking is not subject to the complete ban under the 1st position.

Study aids, laboratory background

CAD laboratory with electronic manuals and online support materials for the current CAD software.
