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.
Export & Co-simulation
Hydraulics don't exist in a vacuum. They are a part of industrial systems that require cross-domain expertise, combining mechanical, electrical, thermodynamic, hydraulic, pneumatic and other components.
Modelon provides tools and expertise for most types of mechatronic systems that incorporate hydraulics, including:
Typical component-level applications include:
Whole system applications include:
The Hydraulics Library fits a large range of hydraulic applications, including vehicle shock absorbers. Shock absorbers built with the Hydraulics Library are compatible with suspensions in the Vehicle Dynamics Library, enabling full-vehicle dynamic analysis. This makes it possible to analyze dynamic behavior such as damping force with respect to damper acceleration. The Hydraulics Library also accommodates variable temperature effects, enabling users to analyze the impact of temperature on performance.
Power steering adds extra hydraulic energy to a vehicle's steering mechanism. The Hydraulics Library contains all the required components for this type of application, such as power steering valves and pump. It is fully compatible with 3D-mechanics and the Vehicle Dynamics Library, allowing users to model the entire steering mechanism.

The example above demonstrates the simulation diagram of a linear drive. It is built with a linear actuator modeled with a cylinder. A hydraulic motor is used instead of a rotational actuator. The load is coupled via a spring to the cylinder.
