Simulation framework of fluid power components for integrated and consistent engineering
The wide range of possible circuit concepts and components, as well as still insufficient Industrie 4.0-compliant project planning, are obstacles on the way to Industrie 4.0-compliant fluid engineering systems. The aim of BaSys4FluidSim is to improve the Industrie 4.0-compliant project planning of fluid engineering systems. Particular attention is paid to taking into account the specific characteristics of the fluid power industry, where most of the know-how, detailed models, data and parameters usually lie with the component manufacturers.
| Benefit | Procedure |
|---|---|
| Uniform, manufacturer-independent preparation of component characteristics | Definition of standardised characteristics |
| Automatic query of component features | Management shell with design-relevant component features |
| Efficient parameterisation of simulation models | Management shell with model description for simulation-relevant data |
| Feedback of operationally relevant properties for analysis and support | A BaSys-compliant way to customise the simulation |
Simulation framework of fluid power components for integrated and consistent engineering
Due to their high forces and dynamics combined with small dimensions, fluid engineering systems will continue to be elementary components of flexible Industrie 4.0-compliant production systems in the future. Simulation models are often used to design fluid power systems. The creation of simulation models and thus the design of fluid power systems is currently characterised by a high level of effort. The effort is justified by a high number of possible circuit concepts and a high number of potentially available fluid technology components for their realisation. Therefore, the concepts of the basic system Industry 4.0 (BaSys4.0) are to be applied and further developed in the project. As a result, the interoperable availability, the digital integration capability and the consistency of product lifecycle management data for component-based fluid engineering simulation models are to be increased.
In BaSys4FluidSim, a SimI4Komp is introduced for this purpose, which consists of an administration shell and a simulation model. The administration shell (AAS) represents the virtual representation and the functionality of an object (e.g. a fluidic component) and functions as a standardised interface. The simulation model (SimAsset) has interfaces with defined characteristics on the outside, whereby the inside of the simulation model is not further specified and is to be realised as a Functional Mock-up Unit (FMU). The services defined in the management shell of SimI4Komp are to be used on the one hand for access and interaction with the underlying simulation models and on the other hand for interaction with the management shells of real components (type or instance). The interaction takes place via the interoperable feature or service endpoints of the management shells. These are implemented with one of the BaSyx software development kits.
The goals envisaged in the project are validated using the example of a servo-hydraulic press from Parker. Through the concrete implementation of all relevant aspects and their validation on the practical demonstrator, a blueprint for future applications of BaSys concepts in industry is created.
