Lineární elektrohydraulický pohon zvedané plošiny

Abstract

The aim of the master thesis is to design an electro-hydraulic drive of lifting platform for applications in theatres. The introduction deals with appropriate choice of hydraulic circuit controlled by means of valve or variable displacement pump. After that energetic comparison of two proposed circuits was carried out. The kinematics of mechanism was solved at first. Design and calculation of hydraulic circuit in steady state were performed based on force diagram. Moreover thesis deals with basic dynamics calculations. Finally, the result is hydraulic circuit for lifting scissor platform. The drive is realized by using displacement control of variable displacement axial piston pump.
