Helical compression spring is used in multiple applications. It is mainly used for energy storage, shock absorber or damper, motion transfer etc. It is observed that the axial force applied on the helical spring do not transfer completely at the other end. Some amount of forces transferred in lateral direction. In this paper, the study of lateral forces is presented. Different possible causes of the generation of lateral forces are explained. Four cases of helical compression spring such as regular, conical, barrel and hourglass are presented. The regression model demonstrates the percentage of lateral force against axial load.
