Labs

Familiarise yourself with the Smath interface and complete all your calculations and assignments in this system.

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.

Requirements, evaluation and grading
Mid-term study requirements

During the semester, the level of knowledge acquired will be tested by writing 3 20 point and 2 20 point assignments. At least half (10 points) of the points obtained in each section must be achieved, and in the case of an unsuccessful exam, a make-up exam will be given.

Exam requirements

The final exam can be written by a student who has completed the submission of the design assignment to an acceptable level by the deadline.

Generative AI usage

Use of GAI tools is not permitted for solving assignments. This means GAI tools cannot be used to complete formative or summative assessments, and using GAI constitutes academic misconduct. The use of AI tools for spelling and grammar checking does not fall under this prohibition.

Study aids, laboratory background

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