Hydraulic component standard symbol library
Characteristics of AMESim (1) AMESim is used by engineers and technicians. The language of modeling naturally adopts engineering language, multi-disciplinary modeling and simulation environment, and realizes multidisciplinary mechanical, hydraulic and pneumatic on a unified platform. Modeling and simulation in the fields of heat, electricity and magnetism, and the physical connection between modules in different fields enables the analysis of multidisciplinary coupling characteristics. These features help users free themselves from cumbersome mathematical modeling and focus on the physical model system itself. AMESim provides a complete, superior simulation environment and the most flexible solution for complex systems in a multidisciplinary field. Users can study the dynamics of any component or loop with its friendly, application-oriented solution.
(2) AMESim's intelligent solver can automatically select the best integration algorithm according to the mathematical characteristics of the model, and dynamically switch the integration algorithm and adjust the integration step according to the characteristics of the system at different simulation times to shorten the simulation time and improve Simulation accuracy. The embedded automatic mathematical discontinuity processing tool solves the killer level discontinuity problem in mathematical simulation. The partitioning calculation of large hydraulic pipe network systems and the distributed calculation of batch processing and design exploration greatly reduce the time for complex system analysis and optimization.
(3) AMESim is a multi-level modeling and simulation platform. It provides a multi-level modeling mode from solution design to functional design to geometric design on a unified platform. It retains the mathematical equation level, block diagram level and basic. Four levels of modeling at the element level and component level. Different users can choose the appropriate modeling method according to their own characteristics and expertise, or a combination of multiple ways. It not only ensures the flexibility of different modeling models for different problems in different design stages, but also ensures that the design models of different stages can be continuous and inherited. The basic element level modeling method is based on the concept of AMESim basic elements, that is, the minimum elements that constitute the engineering system extracted from the physical system, so that users can use as few elements as possible to establish the engineering system and A complex model of component functionality.
Application on the A380 In the field of aviation, AMESim can solve problems such as aerospace control, landing gear, engine, fuel, environmental control and lifesaving systems. With its own advantages, AMESim has become the platform-level tool of choice for many aviation giants in research and development worldwide. For example, Airbus, Boeing, Eurocopter, and European Aeronautic Defense and Space (EADS), which we are familiar with, have applied AMESim to the daily R&D process and have actually improved R&D efficiency and reduced R&D costs.
Recently, Airbus has once again attracted the attention of the world with its A380 series. The A380 is currently the only passenger aircraft in the world that uses a full-caliber length double-deck cabin and a 4-channel. Its emergence will end the 30-year monopoly of the Boeing 747 in the large transport market, rewriting the history of human aviation. At the same time, the A380 has once again established Airbus's position in the world of aviation.
Behind the A380 scenery, we can easily imagine the difficulty of design and development: in terms of software, it uses advanced flight control system, and installs entertainment system, lighting system, emergency system, etc. in different locations according to different layout requirements of customers. The device has a complicated structure. At the same time, the A380 has a large body, and there are 750,000 screws, rivets and other fixed parts required to assemble only its giant wings. Therefore, compared to other types of aircraft, the A380 series must use more composite materials to make the body lighter.
Messier-Bugatti, a subsidiary of SAFRAN, is a world leader in the design of aerospace ground-related systems and has been playing an active role in ensuring the success of the Airbus ultra-widebody A380 technology worldwide. In the A380 project, Messier-Bugatti faced one of the biggest technical challenges: designing a new and unique hydraulic powertrain for the Airbus A380 super wide passenger aircraft ground steering system, and evaluating the new hydraulic power steering once designed. What kind of risk will result if the system overheats. On the other hand, in the early stages of project development, Messier-Bugatti needed to integrate and optimize the local electro-hydraulic energy system to achieve the best compromise between size and system performance.
In response to the challenges of the R&D process and achieving the stated goals, Messier-Bugatti chose AMESim in the early stages of design. For example, the HYD hydraulic library, HCD hydraulic component design library, TH thermal library, THH thermal hydraulic library, and THCD thermo-hydraulic component design library in the AMESim platform are used to solve the final system performance goal under the premise that the control hydraulic fluid can not overheat. The problem. The successful application of AMESim allows them to optimize the size of all critical systems to ensure that the system provides the necessary power while adhering to strict weight constraints.
The new system model built by AMESim allows Messier-Bugatti to not only analyze the behavior of the hydraulic system (from performance, stability, etc.), but also to observe the heating characteristics of the hydraulic system and the need to evaluate the use of heat exchangers. The results of the simulation can be used directly to establish product specifications to guide the design and development of key functions of the hydraulic power system (tank, pump, accumulator). Messier-Bugatti has benefited from the extensive experience of using AMESim software to build predictable system performance models and has contributed to the A380's ultimate in the sky.
