Abstract This study aims in determining the stress distribution in elliptical cross-section helical springs with small helix angle (less than 10°, often termed as close-coiled springs) considering the effect of wire curvature, subjected to axial static load. We present both analytical and finite element analysis, validated by an experimental study conducted on an actual automotive valve spring. A novel analytical expression for the stress distribution in such springs is developed based on the… CONTINUE READING
