massiverLEICHTBAU 19 Summary Danksagung Achieving more together Danksagung Der Forschungsverbund Massiver Leichtbau Inno vationsnetzwerk für Technologiefortschritt in Bauteil Prozess und Werkstoff Design für massivumgeform te Bauteile der Automobiltechnik ist 2015 entstan den aus dem Ideenwettbewerb Leittechnologien für KMU des Bundesministeriums für Wirtschaft und Energie BMWi Berlin und der Arbeitsgemeinschaft industrieller Forschungsvereinigungen AiF Köln Ziel war es mithilfe neuer Stahlwerkstoffe sowie Bauteil konstruktionen und Fertigungsmethoden den An triebsstrang von Automobilen vom Motor über das Getriebe bis zu den Radlagerungen noch leichter zu machen und trotzdem höchste Lebensdauererwar tungen zu erfüllen An insgesamt 6 Teilprojekten waren zehn Forschungseinrichtungen aus fünf Bun desländern beteiligt Die IGF Vorhaben 24 LN 25 LN 18189 N 18225 N 18229 N 19040 N der FOSTA zusammen mit AWT FVA und FSV wurden über die AiF im Rahmen des Programms zur Förderung der Industriellen Gemein schaftsforschung IGF vom Bundesministerium für Wirtschaft und Energie aufgrund eines Beschlusses des Deutschen Bundestages gefördert Alle Beteiligten danken für die Förderung sehr herzlich From 2015 to 2018 the Lightweight Forging re search network worked across six sub projects on the use of new lightweight construction capabilities for drive trains and chassis The network was founded by the research associations FOSTA AWT FVA and FSV Within the sub projects the areas of materials development design manufacturing and innovation management involved in the supply chain were to be linked with one another In addition to a consideration of the life cycle the following factors played a role here resource efficiency CO2 footprint the identification of obstacles to innovation due to insufficient knowledge transfer and a low preparedness to use new technologies in a process chain with divided responsibilities The primary focus of the studies however was the development of novel material concepts and manufacturing techniques The research network emerged from the Lightweight Forging Initiative founded in 2013 and formed a fourth pillar alongside three other industry supported pro jects that were being conducted Since 2013 a total of 54 steel producing and forging companies had joined forces in this network The aim of this globally unique initiative was to achieve weight savings in passenger cars and commercial vehicles using innovative steel components In Phase I 2013 14 a medium sized passenger car was analysed and the potential for light weight construction of forged components identified A savings potential of 42 kg was determined in the drive train and chassis The initiative entered Phase II in 2015 and carried out tests on a light commercial vehicle up to 3 5 tonnes A lightweight construction potential of 99 kg was to be assessed Phase III began in 2017 at the international level with 39 companies from the US Japan and Western Europe Here lightweight construction potential in the drive train and chassis of a hybrid passenger car and in the transmission of a conventional truck was examined The lightweight construction potential was estimated at 93 kg in the drive train and chassis of a hybrid car and 124 kg in the drive train of a heavy commercial vehicle For more information go to www lightweightforging com
