Abstract

The fuel and cost efficiency in automotive industry is related to the designing of light-weight vehicle components. Main aim of this paper is to show effectiveness of two new optimization algorithms in solving structural design optimization problems. The gravitational search algorithm (GSA) and charged system search algorithm (CSS) are applied to the optimum design of a vehicle component. The results show that both GSA and CSS have a better search capability than the genetic algorithms to find optimum solutions.

Kurzfassung

Die Verbrauchs- und Kosteneffizienz in der Automobilindustrie stehen in Zusammenhang mit dem Design von Leichtgewichtsfahrzeugkomponenten. In den diesem Beitrag zugrunde liegenden Forschungsarbeiten wurden zwei neue Optimierungsalgorithmen, der Gravitational Search Algorithm (GSA) und der so genannte Charged System Search Algorithmus (CSS) verwendet, um Aufgaben im Strukturdesign zu lösen. In dem Beitrag wird die erste Anwendung des CSS-Algorithmus' für Designoptimierungsaufgaben in der Literatur präsentiert. Die beiden Algorithmen wurden zur Strukturdesignoptimierung einer Fahrzeugkomponente angewandt, um zu zeigen, wie sich dieser Ansatz eignet, solche Aufgaben zu lösen. Die Ergebnisse zeigen, dass GSA und CSS-Algorithmus im Vergleich zu genetischen Algorithmen verbesserte Suchfähigkeiten aufweisen und dadurch ein verbessertes Strukturdesign erreicht werden kann.
