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.

Simulation framework of fluid power components for integrated and consistent engineering

The goal of the project was to develop an Industrie 4.0-capable simulation framework for integrated and end-to-end simulation model-based engineering with a focus on:

  • Domain-independent system simulation with a high level of detail across all integration levels.
  • Interoperability for cross-actor use of simulation models while protecting corporate know-how
  • Cross-actor availability of data for or from simulation models throughout the product lifecycle.

To achieve these goals, three functionalities were developed in context within a simulation framework.

The first functionality of the framework (a) allows searching and finding components or component simulation models. Their digital representations are located in the form of AAS in repositories, where they can be searched and queried according to defined requirements for the desired application. Thus, as part of simulation-based product development, the OEM can search the repositories of its component suppliers for required the component data and simulation models of the components needed for the machine.

The second functionality (b) enables a domain and tool independent integration of component simulation models into a simulation environment. On the one hand, this integration is enabled by an automatic parameterization of simulation models with the available parameters from the AASs. The automatic parameterization reduces the time required and the error-proneness of the otherwise usual manual parameterization from a wide variety of parameter sources.Another option is the integration of a complete component simulation model as a Functional Mock-up Unit (FMU). FMUs are based on the Functional Mock-up Interface (FMI) standard and serve to encapsulate simulation models, in the case of co-simulation even including the appropriate integrator. In this way, the FMU-based approach supports flexible, domain- and tool-independent use and, at the same time, protects the know-how of the model manufacturer through model encapsulation.

The third functionality (c) enables the bidirectional comparison of parameters and states between the simulation and the real components in the store floor machine based on their AAS instances. This enables error investigation and correction on the real machine with the inclusion of the simulation model or supports commissioning by allowing parameters already determined in the simulation to be transferred directly to the machine control system. In both cases, the transparency and thus the quality of the decisions to be made is increased for the technical personnel with a significantly reduced expenditure of time.
