Tecosim-Forschungsprojekt: Weniger Rechenzeit bei Crashsimulationen

Im Rahmen eines Forschungsprojektes haben die CAE-Spezialisten am Standort München Einsparpotenziale bei der Rechenzeit von Crashsimulationen herausgearbeitet / Das Ergebnis überrascht: Um bis zu 25 Prozent kann die Rechenzeit reduziert werden

(PresseBox) (Rüsselsheim, )
Die numerische Simulation verschiedener Crashszenarien ist bei der Entwicklung neuer Fahrzeuge ein wichtiges Instrument. Hochdynamische und teilweise nichtlineare Prozesse werden mit speziellen Finite-Element(FE)-Programmen dargestellt. Obwohl heutige Fahrzeugmodelle für die Crashsimulation schon circa drei Millionen Elemente beinhalten, besteht der Wunsch nach einer weiteren Detaillierung. Denn viele bisher nur grob abgebildete Bauteile haben einen erheblichen Einfluss auf das Crashverhalten.

Mehr Detaillierung bedingt höhere Rechenzeiten
Eine größere Detaillierung erhöht aber auch die erforderliche Rechenleistung. So rechnen aktuelle Modelle je nach Code und Hardware zwischen 24 und 48 Stunden bei einem Zeitschritt von einer Mikrosekunde. Um beispielsweise Gussbauteile sauber abzubilden, müsste der Zeitschritt auf
