Approach for a Data-Management-System and a Proceeding-Model for the Development of Adaptronic Systems

Existing proceeding-models for the development of mechatronic systems intend a mostly independent development of single components, like the mechanic structure, the electronics, etc., starting from a combined over-all-model. Following the understanding of adaptronics as an advancement of mechatronics in the LOEWE-Center AdRIA (AdRIA – Adaptronic - Research, Innovation and Application), a clear division of the development is not advisable, because of the high structural integration of adaptronic systems. Because of this, it’s necessary to develop the whole system by using a permanent alignment of values between the single components. This high grade of data transfer and the high number of relations between the components lead to a complexity that can only be handled by the use of a Data-Management-system. An approach for a Data-Management-System for the development of adaptronic systems by the Department of Computer Integrated Design, as part of the LOEWE-Center AdRIA, intends to extend the functionality of existing Product-Data-Management-Systems. The idea is to model the over-all system in the Data-Management-System at first, using the partitioning of the system into the five elements of active structures: excitations, structural components, actuator systems, sensor systems and signal processing. Furthermore the characteristic parameters of single components and the correlations between these parameters are captured. In addition the requirements of the adaptronic systems are captured and deposited in the Data-Management-System (DM-System). An integration-layer is used, to integrate the data and models of the different disciplines to the DM-System and to the generated over-all model, during the development of the adaptronic system. The database of the DM-System contains a standardized over-allsimulation model of the adaptronic system, which uses the same partitioning of the system to the different elements as the overall-system model. The consistent structure of the system-model, simulation-model and integration-layer is used for an automated over-all-simulation of the adaptronic system. Using the automated over-all-simulation changes in the adaptronicsystem-behavior can be calculated, when changes in single components become available. Using the deposited requirements, these changes can also be valued. An analysis of existing proceeding-models for the development of mechatronic systems shows, that they are only partly suitable for use in the given approach. Therefore a new proceeding model was developed as an advancement of existing models. The new model shows an equitable solution for the development of adaptronic structures by using Data-Management-Systems.

The W-Model – Using Systems Engineering for Adaptronics

Abstract Active systems are characterized by a steadily increasing degree of structural integration of electronic components into mechanical structures. To enable a systematic development process supporting continuous improvement the so-called W-model as a new process model for the development of active system is proposed. The W-model takes into account the mutual cross- domain dependencies in adaptronic development. Following the principles of systems engineering, a system model based on the requirements is defined in the early phases of product development. The system model contains requirements, functions, components and the corresponding properties and parameters as well as their interdependencies. The resulting dependency-network is used during the discipline-specific detailed development for a control of the development process. Therefore integrated system simulations can be derived from the system model in which discipline-specific solutions are integrated and evaluated. Through interdisciplinary virtual validation and verification of partial and cross-disciplinary results during the development process, errors and inconsistencies are identified and can be corrected directly. Due to the continuous use of the system model in all development phases knowledge about dependencies between system elements, can be transferred into all disciplines.

Meta-data-Model for the Development of Adaptronic Systems

Active systems are characterized by an integration of electronic components into mechanical systems and can be distinguished into mechatronics and adaptronics. In adaptronic systems the electronic components are full structural integrated. The Department of Computer Integrated Design (DiK) has developed the W-model as a new proceeding model for the integrated development of adaptronic systems which is based upon a virtual cross-disciplinary integration and verification in all phases of product development. Therefore the W-Model insists on the use of special development environment which is based on the product data management functionalities. In this paper a proposal for a meta-data-model for such an environment is presented. Following the W-model the meta-data-model allows the definition, import and analysis of complex system models, the derivation of hierarchic requirements-, function- and product structures and the definition of integrated system simulations for the virtual verification of results.
