To enable failure simulation as a substitute of testing on real machinery for validation of functional safety; typical hydraulic failures are added to safety-related components of an in-house Modelica hydraulics library. This library is then used for the verification and validation of functional safety of a hydraulic test bench. Moreover; error propagation is considered.
Keywords: Functional safety; hydraulics; simulation; failure modeling
