Abstract

Stresses in elliptical-cross-section coil springs become small as compared to other springs used in practical machines at a certain aspect ratio. This article presents a simplified stress expression for designing the elliptical-cross section coil springs. The stresses obtained by the present design formula are compared with those obtained by numerical methods. It is ascertained that the present formula is applicable to design the elliptical-cross section-coil springs.
