Entwicklung eines industriell hergestellten Versorgungs- und Technikmoduls fuer mehrgeschossige Einfamilienhaeuser

Normally, traditionally built houses as well as prefabricated houses have similar components as regards building technology. For example, this includes the supply with power and gas, the heating technology, the supply and disposal of water, sanitary equipment, communication technology as well as staircases and an optional lift. The current research project aimed at the concentration of these technologies to form a so-called supply and technical (VT) module for universal applications as far as possible. As an example, a product suitable for series production and adaptable to individual conditions was to be developed and produced for series production. The cost-efficient high-quality steel frame design proven in module construction was the starting point for this as a static support structure. During an intensive planning phase predictive requirements were collected and designed to form a model. Static calculation showed that the VT modules could compatibly be placed one above the other for houses with up to 5 floors. The concept is based on a strict separation of the VT modules from the other rooms in the building. All interfaces have largely been standardized and are of the plug-in or screw-type. Thus, building units erected with the traditional building technology, room module and prefabricated wood design can be interconnected easily. During a modernization of old buildings with multiple floors the specially designed VT modules can be 'docked' to existing buildings. A major advantage, for example, is a subsequent and easy retrofit of a building with a lift without essentially interfering with the existing buildings. A selection of the appropriate support heights allows a relatively simple adaptation to the different existing floor heights. A selection of the materials for designing the facade permits an optional adaptation to the existing buildings. Due to the results from this project, planners and architects may use a module which has a high degree of quality, reduces the construction time and makes the building phase more independent of atmospheric influences.

Entwicklung eines Verfahrens und Ermittlung von Werkstoffkennwerten fuer eine beanspruchungsgerechte Auswahl verschleissbestaendiger Staehle

A generally valid selection method for steels was developed on the basis of a tribological systems analysis according to DIN 50320 in close cooperation with steel producers and representatives of several industries. The focus was on abrasive and hydroabrasive wear, sliding wear, impact wear and inclined impact wear, as well as erosion by cavitation. Comparative test stand analyses of different steels provided information on their material characteristics. The investigations were carried out in different tribological conditions and partly also in corrosive conditions. Parallel to the investigations, a PC-supported program system for materials selection was developed that will serve for archiving and quick reference.Available from TIB Hannover: RR 7808(277) / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekSIGLEStifterverband fuer die Deutsche Wissenschaft e.V., Essen (Germany).

Weiterentwicklung der Stahl-Kunststoff-Hybridtechnologie fuer den Fahrzeugbau

The combination of different materials for the optimisation of structures and components in the range of vehicle engineering, gains increasing importance. This research report shows the possibilities and the potential of an innovative technology for vehicle manufacturing, the reinforcement of sheet-metal structures by injection-moulded plastic elements. Thereby a general overview over the principle build up of this kind of components, under consideration of different methods and materials, is given. Components, already realized by this hybrid technology, will be presented. Especially the advantages of different material combinations are considered in detail. Based on the overview of existing components a substructure has been chosen to examine the structural behaviour by means of quasi static testing and to evaluate the simulation of the structural characteristics with the finite element method. The tests verify the performance characteristics of the hybrid construction against not reinforced components. In comparison to conventional components, hybrid components show the combination of a high integration potential and good mechanic characteristics at reduced weight. Thereby the chosen combination of plastic- and steel structures provides the possibility of a dimensioning of the components adapted to the relevant load-cases.
