Virtual model of an electro-hydraulic system

Abstract

This paper deals with the design of model of electro-hydraulic system with failure simulation feature. The fundamental causes and effects of failures of electro-hydraulic system are summarized. Virtual Simulink model of electro-hydraulic system has been developed and implemented in compliance with performed FMEA (Failure Mode and Effects Analysis). Subsequent experimental part focuses to the simulation of selected failures on electro-hydraulic system model. The results of simulation of failures are shown in time response characteristics of monitored variables.
