OpenHydraulics

The hydraulics library is a free Modelica library that can be used to model hydraulic components and circuits.

Library description

Hydraulic circuits are commonly used in modern machinery, especially where very large power density is required. Examples include earth-moving equipment, farming and forestry equipment, and in manufacturing. More recently hydraulics is also used in automotive and transportation for energy recuperation in hydraulic hybrid drivetrains.

The library is built up in a modular fashion, starting from basic fluid phenomena modeled in the "Basic" package. These basic models are then combined into models for hydraulic components (Cylinders, Lines, MotorsPumps, Sensors, Valves, Volumes). Finally, these components are incorporated into example circuits, such as a pressure compensated load sensing circuit. To develop your own model, it is best to start from a model in the "Circuits" package and modify it to fit your needs.
