The simulation of pneumatic and hydraulic systems helps improve your understanding of complex relationships and interactions within the system and raises your awareness of existing optimization potentials

Simulation and modeling of fluid power components and systems

Fluid power drives and controls can be found across all industries. Whether they are used to transport liquids or gases, or to transmit power: minimum pressure losses and vibrations in the overall system along with efficient fluid transport are often decisive factors for the competitiveness of the final product. Due to the non-linear properties of fluid power systems, spreadsheet-based design approaches have significant limits. In order to increase performance and efficiency of fluid power systems, its important to consider the fluid circuit, its controller and the connected mechanical and electrical components as a whole for the best results. The most effective way to do so is to use software for simulating your fluid power systems.

Simulation of Hydraulics

Advanced digital control engineering and elaborate valve systems achieve unprecedented quality levels in terms of functionality, reliability and precision. Power peaks can be attenuated by hydraulic accumulators which allow for significant cuts in the plant’s energy consumption. For first-class results, the hydraulic lines, accumulators, valves and actuators are not considered separately, but as a complete system including closed-loop controls as well as electrical and pneumatic auxiliary components. System simulation is a well-established tool for incorporating the advantages of hydraulic and electrohydraulic drives into competitive products.

Safe and efficient pneumatic systems in automotive engineering

Air springs, air brakes, exhaust gas after-treatment, pneumatic control lines and actuators in transmissions: pneumatic systems play a key role especially in commercial vehicles. Pneumatic simulation is an excellent way to find early answers to a number of questions in the design phase. For example:

  • Can the required pressure be provided in any situation?

  • How long will it take to build up the required pressure and how fast are the transmission paths?

  • Is the pneumatic system subject to unfavorable pressure fluctuations?

  • What configuration is best for optimal performance with low energy consumption?

  • How to dimension compressors and accumulators?

Pneumatic simulation for energy-efficient air supply and air conditioning

Air conditioning systems use lower pressures than typical pneumatic applications. Physical correlations are, however, similar. Due to pressure drops, branched systems and the challenge to come up with low-energy low-cost plant designs, the following questions are crucial to product development.

  • How should the system be designed to provide the required air volume at each of the air outlets?

  • What is the optimal configuration of cross sections and orifices?

  • Which air flow can be delivered to which outlet? A simulation model allows you to find the best suited configuration early in the conceptual phase.

Optimal design for hydraulic drive systems in mobile work machines

Whether in mining, agricultural or construction machinery – hydraulic travel and work drives are widely used due to their high power density and flexibility. Efficiency of the hydraulic system is crucial to economical operation and compliance with statutory and regulatory requirements. Simulation will assist you in the optimal selection and dimensioning of the accumulator and in hydraulic transmission designs adjusted to the driving cycle in work operations. Besides the optimal design of control and pressure lines for work drives, valve selection as well as pump and cylinder design, but also stable controls are vital. System simulation helps you keep it all manageable and find the optimum balance.

Fast and economical handling of workpieces through pneumatic simulation

In automation technology, pneumatic actuators enable high processing speeds. At the same time, pneumatic systems are very economical and robust low-weight solutions. They are frequently used for loading, unloading and positioning workpieces. For best results, it is crucial to find the perfect combination between electrical controls, pneumatic actuators and mechanical components. The objective is to design inexpensive, high-speed, high-precision systems with great energy efficiency. Virtual commissioning of the machines allows you to run reliable functional tests before the machine is even built.
