Understanding multiple parameters affecting static and dynamic performances of composite helical springs

Composite helical springs (CHSs) are mainly used in transportation and aerospace fields, such as automobile suspension, railway bogie and aircraft engine systems. It has become a trend to replace the traditional metal helical springs with CHSs with the advantage of energy conservation during service and emission reduction during manufacturing. The advantages of CHSs such as low weight, high specific strength, high specific modulus, corrosion resistance, fatigue resistance and high strain energy storage capacity mean that it has great development potential. The static and dynamic performances of CHSs together determine whether they can be used on a large scale in the engineering field. The static performance of the CHS determines their service-load range and the dynamic performance determines the service life and safety performance of CHSs under dynamic load environmental conditions. Therefore, it is an important task to optimize the static and dynamic performance of CHSs. To provide a reliable reference for the development of CHSs, this review analyzes the important factors affecting the static and dynamic performance optimization of CHSs from the perspectives of theory, finite element method (FEM), and experiment. In addition, the outlook in the research of CHSs are discussed. (C) 2022 The Author(s). Published by Elsevier B.V.
