RESEARCH AND APPLICATION OF UNIVERSAL REGULATION SYSTEM IN ORDER TO MASTER THE SOURCE OF MECHANICAL SYSTEMS EXCITATION [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 In general terms the mechanical systems (MS) means the system of driving and driven machines arranged to perform the required work. We divide them into MS operating with constant speed and MS working with a range of speed.

ANALYSIS OF THE IMPACT OF FLEXIBLE COUPLINGS ON GEARBOX VIBRATIONS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2016 Dangerous vibrations of mechanical systems’ components are causes of failures and reduction in service life, as well lead to negative effects on the environment and the health of operators. In order to reduce these unwanted vibrations, it is necessary to
