Příspěvek ke zkoumání statických a dynamických vlastností regulovaného elektrohydraulického pohonu

Abstract

This dissertation deals with electrohydraulic drives with the possibility of recovery potential energy. The recovery potential energy occurs for example on devices for lifting and lowering the load material when hydrostatic converter operates in motor mode. In this work there are created mathematical models and simulation models of the dynamics behaviour of investigated electro-hydraulics drives. There are described three approaches to mathematical modelling and simulation. Mathematical models are verified on designed and constructed experimental devices. Energy balances in selected operating conditions are evaluated on the bases of the results of experiments and simulations.
