Design method, performance investigation and manufacturing process of composite helical springs: A review

Abstract

Composite helical spring has gained considerable attention due to its high strength to weight ratio and corrosion resistant. It can also be utilized for different applications such as automobile suspension and railway bogie. Therefore, its design method and performance investigation are the research hotspots in the application field of composite structures. This work attempts to review most of the studies carried out on the design method of composite helical springs, including material selection, structure design, performance matching design and optimization design. Moreover, important research results on the performance investigation and manufacturing process of composite helical springs are also highlighted. Finally, the emerging trends in the research of composite helical springs are discussed.
