Design and Analysis of Wave Spring for Two Wheeler Rear Suspension System - A Review

Since many years there is so many research work done on helical spring due to its vast range of working and reliability in various sector, like machines, automobiles etc. All researcher have modified design, changed materials for various purpose. But the conventional spring still in use. Now, with change in time and technology better to find alternative option for it. Wave spring which is different from conventional design, was first conceptualized by the SMALLEY Industries, U.S.A. in 1990’s for purpose of to keep machine component connected by spring pressure. They use the Hooke’s law while designing of it. Wave spring occupies 50% less space than conventional spring, also it have long lasting effectiveness and good durability. For the two wheeler rear suspension system wave spring is designed with the same dimensions of helical spring. The spring is designed and analyzed both theoretically and numerically. Load is considered as the bike weight and two person weight. Structural steel and copper alloy are taken as the spring material. In theoretical analysis the analytical equations are used where as in numerical analysis the structural and fatigue analysis is performed. This present study focuses on the selection of the best spring with the best material for the two wheeler rear suspension system. Soild works is used for the designing of the spring and analysis is performed by the ANSYS.
