Abu Talib, Abdul Rahim and Ali, Aidy and Soliman Mosleh Hamdan, Gehad Goudah and Che Lah, Nur Azida (2010) Developing a composite based elliptic spring for automotive applications. Materials and Design, 31 (1). pp. 475-484. ISSN 0261-3069

Abstract / Synopsis

An automotive suspension system is designed to provide both safety and comfort for the vehicle occupants. In this study, finite element models were developed to optimize the material and geometry of the composite elliptical spring based on the spring rate, log life and shear stress parameters. The influence of the ellipticity ratio on the performance of woven roving–wrapped composite elliptical springs was investigated both experimentally and numerically. The study demonstrated that composite elliptical springs can be used for light and heavy trucks with substantial weight reduction. The results showed that the ellipticity ratio significantly influenced the design parameters. Composite elliptic springs with ellipticity ratios of a/b = 2 had the optimum spring parameters.
