• Motor Vehicles, Semester 1, position 1

The aim of the course is for students to acquire knowledge and practical skills in the field of CAD modelling of road vehicle systems, with a focus on parts, assemblies and their interaction. Students will master the techniques of 3D modelling, preparation of documentation and analysis of basic functions of components and systems.

Upon completion of the course, the student will be able to: 1. Analyse the structure of complex vehicle systems (steering, suspension, power transmission, vehicle supporting structure...); 2. Create and edit 3D models of components and systems using advanced CAD tools; 3. Create and edit technical documentation for the manufacture of parts and their control; 4. Prepare for manufacture or 3D printing; 5. Form a parameterized CAD model of a part or assembly based on a scanned model.

Introduction to the systematic approach to vehicle modelling (categorization and function of subsystems, modelling methods); Overview of CAD/CAE tools in the automotive industry (history, trends and current tools, Siemens NX, Catia V5, FreeCAD...); Component modelling (prismatic and freeform shapes, parametric modelling); Surface modelling (Class A Surfacing); Assembly modelling (connecting parts, degrees of freedom, collision detection and kinematic models); Functional modelling of vehicle subsystems (suspension, steering, vehicle supporting system, power transmission); Reverse engineering and photogrammetry (scanning parts and creating CAD models, scanners and software); Integration of CAD models into a vehicle digital twin.

Basic 3D modelling of components in CAD software (e.g. SolidWorks, Siemens NX, Catia V5, FreeCAD...); Assembly modelling: suspension and steering systems; Creation of parametric models and analysis of geometry variations; Preparation and export of models for simulation; Photogrammetry, 3D scanning and processing of STL/OBJ files for reverse engineering; Creation of a digital model of a component using scanning; Students’ project: modelling and analysis of the selected vehicle system (e.g. front suspension, subframe, gearbox); Presentation and documentation of the CAD project (technical drawings, report, video presentation).

No special requirements.
