Acquisition of basic knowledge of designing and constructing machinery elements and structures. Mastering the methods of construction and design process. Developing skills of teamwork and interconnecting knowledge and skills in various fields of Mechanical Engineering. Training for further study.

After the attended course, students gain knowledge about: • Through the design stages they will be able to selects the optimum variant design from technological and economic point of view - Techno-economic analysis, • Applying technical directives and regulations in the machine design and putting the product on the market, • Evaluate the operational capacity of pressed joints, • Resolves advanced problems with measuring chains, • Check capacity of thin and thick-walled pressure vessels from strength point of view, • Make a selection of welded joints in terms of mutual position of the parts to be joined, • To form and do the technical documentation of given mechanical construction.

Stages in the process of machine designing and constructing. Definition of executors for basic, partial and general functions. The formation of variant solutions and their evaluation - techno economic criteria. Selection of a compromise solution. The variant constructions. The product life cycle. Unification and typization. Measuring chains. The rules and regulations in the machine design process and constructing. Introduction to basic concepts and regulations related to construction processes in mechanical engineering. The necessity of compliance with regulations. Conformity Assessment. Harmonized standards. CE marking of products. Placing products on the market. Pressure vessels. Thick and thin walls pressure vessels. Operational stresses. Thermal strain. Critical stresses in static conditions. Selection of welded joints in terms of mutual position of parts to be joined.
