Modelon's Pneumatics Library is used to verify and optimize the design of complete pneumatic systems throughout a product lifecycle.
Applications include suspension and brake systems, machine tools, heavy-duty pneumatic tools such as jackhammers, impact wrenches and drills.
The Pneumatics Library provides components for modeling cylinders and motors, valves and nozzles, lumped volumes, lines and sensors. Specially designed components can be modeled by modifying library components and users can easily connect components to create non-standard configurations.
Large trucks often use air brake systems. The Pneumatics Library from Modelon offers all the components -- including compressors, reservoirs, valves and chambers -- necessary for this type of application. It is fully compatible with the Modelica Standard Library for modeling the brake caliper and discs and with the Vehicle Dynamics Library for full-vehicle system analysis.
Jackhammers are powered by compressed air, making the Pneumatics Library ideal for studying dynamic effects such as behavior at different working frequencies. The library also enables users to study other effects such as power loss due to leakages and piston mass. The Pneumatics Library is applicable to everything from small handheld jackhammers to large excavator-mounted jackhammers.
The example above shows a multi-position cylinder. This includes three cylinders from the Pneumatics Library: one single rod and two double rod cylinders, one of them with pneumatic stroke cushioning. They are connected by so called ElastoGaps.
Multi-position cylinders consist of typically two or three connected cylinders to reach three or four end positions. There is typically one port for every head-end chamber and one port for the connected rod-end chambers.
