- The overall focus of research in the department is the optimization of energetic processes and machine properties. The emphasis is placed on the reduction of energy consumption by implementing ecological technologies. The research is facilitated by optical visualization methods, which are used for the objectification of numerical simulation data. Optical measuring methods are specially developed to identify the development of dynamically and thermally unstable processes.
- The following phenomena are investigated within the research plan: unsteady turbulent processes with coherent structures, subsonic and supersonic mixing flows in ejectors, cavitation and recrystallization processes driven by a translational and rotational magnetic field.
Department of applied Mechanics
Research in the field of applied mechanics focuses on two key areas. Our prime field of research is into vibroisolation of mechanical systems. Secondly, the department conducts experimental and analytical research into the following areas:
- The mechanical properties of nonlinear anisotropic materials and their mathematical modelling the development of robotized chassis for autonomous mobile robots.
- The mechanics of vibrating systems.
- The construction of controlled dynamical systems.
- A significant part of our research is into vibroisolation of flexible mechanical systems such as a loaded driver’s seat and chassis, or an ambulance couch and vehicle cabs. This task also includes investigation into, and construction of different types of vibroisolation elements such as dampers, springs and combined units, determination of basic characteristics of the flexible elements and of damping properties of rubber and rubber composites. A vibration platform with six degrees of freedom was erected specifically for this purpose top carry out biomechanical research in the field of human body loaded by acceleration in general direction.
The research activity of the department focuses on these aspects of material engineering: thermal treatment, surface testing of materials, surface treatment, thin layers, intermetallics, polymer materials, composites and technical ceramics.
Research in the department focuses particularly on the following areas:
- Theoretical aspects of the machining process.
- Monitoring the cutting process when using a tool with defined geometry of the edge.
- Monitoring the cutting process when using a tool with undefined geometry of the edge.
- Research into the methods of cutting process monitoring by acoustic emission.
- Research into intelligent cutting tools.
- Simulation of the grinding process.
- The department specialises in applying research to solve problems in industry. The particular emphasis is on research into the influence of thermal and mechanical processes on the properties of the parts produced by different technological processes within the branches of metal forming, plastics processing, casting, and welding.
- As far as the technologies of plastics processing is concerned, the research is focused on analysing and optimising the processes of polymer processing, its mixtures and composites, in relation to thermal processes, as well as the rheology of plastic melts and the application of software simulations. This research is applied to increasing the usable properties and quality of the parts, optimising the construction of the moulds, the morphology of the plastic materials and also the non-conventional methods of injection, cooling, etc.
- In the area of metal forming and tribology, the department focuses developing new processes
of production for sheet processing using numerical simulation and control of forming operations and tribological conditions in tools, with the emphasis on improving of stamping´s surface quality.
- Research into the branch of casting is focused on analysing the porousness and crystal structure of the casts, dilatation properties during the casting with metal moulds and on analysing and optimising the metallurgical processes in the production of thin-walled casts.
- In the area of welding, research is being carried out in several fields: observation of welding process parameters, the influence on effective production and quality of fillet welds for MAG welding method, and the optimisation of welding conditions for materials which are quite difficult to weld – e.g. ferrous aluminides. Another area of interest is quality provision for resistance point welding by monitoring the electrical values of the welding process.
