The study programme Parts and Mechanisms of Machinery is one of the basic programmes in the field of machine design. Within this field, top experts are trained in the field of numerical and experimental research and development applicable in all other fields of engineering. The scientific activities of our Doctoral students are focused on machine part optimization, specifically on the torsional oscillating mechanical system optimization, with an emphasis on dangerous torsional vibration magnitude control through the application of pneumatic couplings, research in the control of various sources of vibrations, e.g. automotive gearboxes; drive units of various mechanical systems; etc. Furthermore, attention is given to the area of kinemics and force ratios of spur, helical and non-traditional gear mechanism.
