Weight Optimization of Stainless Steel (SS304) Helical Spring

This study deals with the elaborate design optimization technique for helical compression spring with analytical method. Concentration is made on reducing weight of helical compression spring keeping the induced stresses within permissible limits. The spring is acted upon by compressive force so the spring gets compressed. The entitled work comprises, design of helical compression spring made from wire of solid circular section for a problem and optimizing the weight of solid wire spring by redesigning it with hollow circular section instead of solid circular section. After analytical design procedure the solid wire spring and optimized spring (i.e. spring made from hollow circular wire) are manufactured. After manufacturing of springs, analytical results are validated experimentally and in ANSYS.
