Work Packages and Milestones in the ACODEPT Project

WP1: State-of-the art of the electromagnetic pulse technology, analysis of coil systems and definition of the methodology

In a first phase, a literature survey will be performed, to update the knowledge about the electromagnetic high-velocity forming, cutting and joining processes. In particular, information concerning the coil design will be searched for. Existing coil systems will be investigated and evaluated (advantages, disadvantages, problems to be resolved).

Also at the beginning of the project, the methodology, the detailed research plan and detailed timing will be determined as it will be used throughout the whole project.

WP2: Conceptual design of application oriented flat and cylindrical coils

After extensive knowledge has been gained about coil design, a conceptual design of flat and cylindrical coils will be developed. This will first be done using analytical calculations (magnetic fields, forces, temperature, ...). The goal is to define an initial shape of the coil, which can afterwards be optimised using finite-element techniques.

WP3: Coupled magneto-structural simulation of the electromagnetic forming process

The launch of the design activities will be in parallel to the development of a finite-element model, which enables the simulation of the deformation as a result of electromagnetic forces and will assist the design. As soon as the constructed models are accurate (e.g. based on the comparison with the deformation), the models will be used for coil design and optimisation.

A continuous coupling will exist between the modelling activities and experiments executed on the BWI- and IWU test set-ups. For model refinement, the experimental results and measurements of the process parameters, temperature or deformations carried out on both test set-ups will be used as input data for the finite-element model. The predicted deformation by the model will be compared to the measured deformations during the experiments.

WP4: Material definition for coil systems

Very important in the design process are the material related aspects, more specific the investigation of the most appropriate materials to be used in the coils, field concentrators, housing, etc. So for example the possible application of roll cladded conductor material.

WP5: Investigation of manufacturing techniques for coils

Also coupled with the design is the investigation of suitable manufacturing techniques for coils and their components. Important issues are the design and realisation of the coil turns and the contacts between them, the insulation possibilities to avoid contact problems, etc.

WP6: Manufacturing of coil prototypes

After the coil design has been finished, the manufacturing possibilities are determined and material issues have been investigated application-specific coils will be constructed.

WP7: Testing of coils

These coil systems will be tested subsequently under real conditions in order to obtain information concerning performance, lifetime, etc. Testing and subsequently design optimisation is crucial for the verification of the applicability of the developed methods. The members of the user committee are required to identify different relevant applications to guarantee extensive coil testing.

WP8: Manufacturing of demonstration workpieces

Demonstration workpieces will be manufactured with the manufactured coils. After establishment of a research plan where test materials, diameters and wall thickness and other variables will be selected, the feasibility of the use of the electromagnetic processes will be investigated and evaluated.

WP9: Dissemination of results and project management

In the final work package, the obtained knowledge will be reported and disseminated.
