Several pneumatic and hydraulic components.


Fluid system simulation

Boost energy efficiency and performance of your fluid systems.

Model fluid systems quickly, easily and accurately

Optimize the dynamic behavior of hydraulic and pneumatic components while limiting physical prototyping to the strictly necessary. With a wide choice of components, features and application-oriented tools, Simcenter allows you to model fluid systems for a wide range of applications such as mobile hydraulic actuation systems, powertrain systems or aircraft fuel and environmental control systems.

Simcenter provides you with comprehensive component libraries to support occasional and expert users when modeling fluid systems, from functional to detailed models. The seamless communication between libraries and the accurate modeling of physical phenomena enables the design of any fluid system and the coupling with controls and other related systems in a single platform.

Fluid system simulation capabilities

Powertrain subsystem simulation

Accelerate the design of your valvetrain, cranktrain, fuel injection, lubrication and cooling systems. Simcenter allows you to size your components, assess and optimize your system efficiency and validate your control strategies. You will be able to prepare the integration of your subsystem within the powertrain environment by evaluating the interaction between the different subsystems and with the combustion chamber, and analyze the impact of your subsystem design on engine performance, fuel economy or emissions.

Aircraft fuel system simulation

Handle the challenging task of optimizing fuel pressurization, fueling, refueling and defueling of reservoirs with complex shapes while accounting for aircraft altitude, acceleration, wing bending or twisting. The software helps you model the venting, onboard inert gas generation system (OBIGGS), the fuel distribution network and the global energy management system in order to predict potential issues. You can improve efficiency and reduce weight, volume and energy consumption of your fuel systems while satisfying certification requirements.


Aircraft hydraulic system simulation

Improve the performance of aircraft hydraulic systems by simulating their behavior for different sizing scenarios and flight missions. Simcenter Amesim provides a scalable approach to tackle engineering challenges ranging from low- to high-frequency dynamics. It allows you to integrate your hydraulic system models with those representing interfaced systems, such as electrical systems, landing systems and flight controls, to assess the aircraft performance at large. You can then estimate the system’s degraded performance by simulating how it responds to failures, and find alternative designs to meet certification requirements.


Fluid power system modeling

Assess the overall behavior of hydraulic or pneumatic systems and components. Simcenter comes with a set of predefined functional components for pumps, compressors, valves and actuators, as well as with a series of detailed geometry-based components. You can study the evolution of pressures, flow rates and temperatures in the complete system, and analyze the performance of specific components (valves or pumps), taking into account compressible flow, mixtures of gases, thermal effects, aeration and cavitation.


Heavy equipment actuation system simulation

Design robust, reliable fluid power actuation systems for earthmoving, crane, crawler, mining equipment and more. Simcenter enables you to reduce power generation (such as variable displacement pumps and load sensing), develop new functions (such as self-leveling and control strategies) and improve product quality, robustness and reliability. The software enables you to consider every subsystem, and predict the dynamic behavior of the global fluid power system.


Pump and valve system simulation

Boost the performance of your compressors and hydraulic pumps with Simcenter. Computer-aided design (CAD) import capabilities enable you to easily create a high-fidelity model from the detailed geometry. It helps you meet the increasing demand for high performance: flow characteristics, reduced pressure ripple and precise regulation of pump displacement. In addition, you can solve integration issues earlier in the design cycle, and optimize control strategies to adapt the pump flow according to the actual actuators’ request.
