Hydraulic Motor Drive with Pressure Compensator

The model shows a hydraulic motor drive with inlet pressure compensator and additional brake valves in the consumer lines. The inlet pressure compensator is connected upstream of the proportional directional control valve and effects load compensation only in positive load direction. The volume flow is kept constant by the proportional directional control valve even with fluctuating load pressure. The load pressure in the consumer lines is tapped via the shuttle valve. Because the load can also become negative, there are brake valves in the consumer lines which prevent the load from overrunning. A further task of the brake valves is for safety reasons to shut off leakage-free at halt.

  • What components does the Hydraulics module contain?
    The Hydraulics module contains over 100 different elements for the simulation of hydraulic systems including: pumps/motors, cylinders, brakes, clutches, tanks, volumes, sources, accumulators, pressure valves, flow valves, check valves, cartridge valves, proportional directional control valves, safety valves, filters, coolers, sensors, pipes, hoses, elbows and more. Check out the video tour of the Hydraulics module for more information, or request the Hydraulics Module Sheet for a full list of components.
  • How do the hydraulic components connect to other domains like mechanics, thermal or controls?
    Elements from the Hydraulics module have built-in interfaces to the most common physics domains. For instance, the hydraulic cylinders include 1D mechanical connectors, and the hydraulics volume has a thermal port for heat exchange. Pumps, control valves and sensors include a signals port to receive the control signal or to send sensor information.
  • Does the Hydraulics module calculate temperatures or only pressures?
    It can do both. The Hydraulics module contains an optional Energy Balance that is by default turned off to minimize the number of state variables in the equation system, resulting in faster calculation speeds. With the Energy Balance turned off, the temperature is assumed to be constant throughout the hydraulic circuit, suitable for many power fluids applications. If heat transfer and temperatures are important for the circuit to be simulated, the Energy Balance can be turned on, and all hydraulic volumes will automatically receive an extra state variable for the temperature that will be dynamically calculated based on the inflows, outflows and heat exchange with the environment.
