Modelon's Hydraulics Library is valuable for all industries that develop hydraulic components and applications, including automotive, aerospace and industrial equipment.

 The Hydraulics Library provides models of pumps, motors and cylinders, restrictions and valves, hydraulic lines, lumped volumes and sensors. No special components for splits or mergers are required -- users connect hydraulic components by simply drawing connection lines, making it easy to model non-standard configurations and component designs. 

Benefits

• Ability to combine system and component design in a single tool
• Easy integration into any application domain
• Well suited for control design
• Can be used for real-time applications
• Handles incompressible and compressible oils and cavitation
• Open and customizable for specific user applications

Examples of large applications

Capabilities

Thermal effects

• Conditional thermal effects to catch temperature dynamics and heat transfer

Components

• Over 70 ready-to-use front end components. The library covers everything from standard valves, restrictions, lines, accumulators, pumps, sensors and more
• Components have standard ISO hydraulic schematic icons to easily recognize the environment for application engineers
• Geometry based valve design using Elements. Includes building blocks like different poppet geometries (conical, ball, etc.), spool valves with flow forces and pistons

Animation/ Visualization

• Visualize system behavior with neat animation feature of hydraulic components (e.g. valves, cylinders, volumes), by varying icon position and color brightness for pressure

Hydraulic effects

• Real time capable hose, line and pipe models to catch delays, pressure spikes and water hammer effects. They use  different approaches like frequency dependent friction, delay based or distributed lumped
• Use a large range of predefined standard hydraulic fluids or simply define your own
• Detailed models for variable density, bulk modulus and viscosity
• Gas fraction mixture equations in the hydraulic fluid
• Employ resistance models covering both laminar-, transition- and turbulent region as well as cavitational effect

Model integration

• Interact with models from other domains like controls, pneumatics, vehicle dynamics, liquid cooling and mechanical

Examples

• Simulate, modify or extend any of the 18 complete system examples for different application area

Export & Co-simulation

• Export sub-systems using FMI to use within different tools without the need of Hydraulics license
• Co-simulate several subsystems using various fluids.
