Abstract—A spring is an elastic object used to store mechanical energy. They can twist, pulled or stretched by some force and can return to their original shape when the force is released. Static analysis determines the safe stress and corresponding pay load of the helical compression spring. The present work attempts to analyze the safe load of the locomotive suspension spring with different materials. A typical locomotive suspension spring configuration is chosen for study. In this present work is carried out on modeling and analysis of primary suspension spring (60Si₂MnA) is to replace the earlier conventional steel helical spring (Chrome Vanadium). The work is to reduce the overall stress and deflections of the helical spring by using the new material. This work describes static analysis of the locomotive suspension spring is performed using Ansys 14.0 and compared with analytical results. The spring model is done by using Pro/E Wildfire 4.0 software.
