Simulační analýza lineárního elektrohydraulického pohonu

Abstract

The Master Thesis deals with a simulation analysis of a linear electro-hydraulic drive. The first chapters describe hydraulic drives used in theatres, methods and tools of a system simulation and a position control of electro-hydraulic drives. Before the simulation is executed, main parametres of the given electro-hydraulic drive are calculated, followed by a stiffness and frequency analysis of the two-body system. For modelling purposes, the relevant circuit components are chosen and created their simulation models in the program MATLAB/Simulink. The given circuit is completed with a controller and simulated in order to get the courses of required quantities. Finally, the simulation results are commented and recommendations for the design of circuits with a similar structure are suggested.
