Characteristics of the conducted research
The subject of scientific work carried out at the Department of Mechanical Engineering covers many issues related to the application of modern computer-aided systems CAD/ CAE/FEM in the processes of simulation design and manufacturing. The basic research issues concern propulsion systems and toothed gears. The main currents of research work focus on issues related to increasing the load capacity and reliability of mechanical propulsion systems as well as modeling and testing of lubrication and wear processes. Rapid prototyping techniques and reverse engineering, based on computer-aided manufacturing processes and coordinate measurement methods, play an important role in scientific activity. The works conducted in this area concern the design and analysis of the structure of products manufactured with the use of 3D printing methods, testing their functional properties and mechanical strength. Research issues also include the use of additive technologies in medical engineering, industrial design and their industrial applications with the use of information systems based on the assumptions of the Industry 4.0 structure. Works in the area of modeling and analysis of detachable and inseparable connections are also carried out. Many works are of an interdisciplinary nature, including designing elements used in medicine, rehabilitation and assistance for people with physical disabilities.
