Computer Aided Engineering Design with SolidWorks

Course developer

Course abstract

The aim of the studying course is to get knowledge about computer aided design and possibility to use CAD software to solve engineering problems and process automatization. Students learn objects modelling principles of parts of simple and complex shapes and automatic creation of components drawings. Knows possibilities of Parts and Assemblies 3D digital prototypes strength simulation. Able to perform mechanism motion simulations by calculating system kinematic and dynamic parameters. Develops of the technical documentation of the project for a machine/ equipment/unit (models, drawings, specifications, dxf files, test results).

Learning outcomes and their assessment

1) Knowledge – Students understand the principles of modelling of simple and complex shapes and surfaces and are familiar with methods of digital prototype design of parts and assemblies with several features and standard mates. They know the possibilities of automatic creation of parts and assemblies’ drawings. Knows possibilities of Parts and Assemblies 3D digital prototypes strength simulation. Knowledge is appreciated in tests and laboratory works.
2) Skills – Students know to design parts with several features, create automatic views and sections and perform drawings according LVS and ISO standards. Is able to make motion analyse of the mechanisms and the strength analyse of the Parts and Assemblies. Skills are appreciated in tests and laboratory works.
3) Competence – ability to apply professional knowledge and skills in practical work and studies to solve different engineering problems. Able to analyse the results of product design, as well as to make necessary adjustments. Competence is appreciated in tests and laboratory works.
