Entwicklung eines wissensbasierten Informationssystems zur rechnerischen Lebensdauervorhersage

The automotive manufacturer oppose the increasing competition with shorter development times and reduced costs. For this new development tools are necessary specially for the reduction of the experimental development expenditure. If computer aided fatigue life prediction methods supply reliable fatigue life values the experimental stage of development can be reduced. These computer simulations have to include internal experiences, of companies rules of improvement, facts, experimental results and the proved calculation methods. Together with the Adam Opel AG in Rüsselsheim the Fraunhofer-Institut für Betriebsfestigkeit has developed the knowledge based information system FALIXS (FAtigue LIfe EXpert System) for fatigue life prediction of automotive components. It is an effective tool for the design of fatigue resistant structures.
