Experimentelle Untersuchung zu faser- verbundgerechten Crash-Wirkmechanismen bei axialer Druckbelastung/Experimental Studies on Fiber Com- posit-appropriate Crash Mechanisms under Axial Pressure Load

Abstract: INHALT Der Leichtbau und die Crash-Sicherheit im Passagiertransport, wie etwa bei Schienen- und Fahrzeugbau nehmen stetig an Bedeutung zu. Besonders bei neuartigen Antrieben mit Elektromotor zeigen sich neue Sicherheitsanforderungen beispielsweise für den Batterieschutz. Daher sind Untersuchungen zur Entwicklung von leichten Crash-Energie-Absorbern von großer Relevanz. Im Rahmen der vorliegenden Arbeit wurden deshalb sechs verschiedene Crash-Wirkprinzipien experimentell untersucht und ausgewertet. Bei fünf dav… Show more

“…Due to the increase in energy absorption of approx. 30-50 % by applying the inversion principle compared to simple crushing (see [6]), the inversion crash mechanism was chosen for frontal, side and rear crash absorbers. For this purpose, the internal study provided proof of function on individual crash tubes.…”
