Dynamika hydraulického obvodu pro zkoušení důlních mechanizovaných výztuží

Abstract

This diploma thesis deals with the dynamics of a hydraulic circuit for testing mechanized mine supports. The processes of testing mechanized supports are given as well as the description of mechanized supports and their hydraulic circuit. Subsequently the description of a measuring instrument and the measurement follows. The mathematical model is completed in Matlab-Simhydraulics according to the measurement results. Finally, an optimization of hydraulic circuit is proposed.
