A Review of Stress analysis of Helical Compression Spring for Toggle Switch Mechanism

The country India is good for becoming a supplier of the goods and services. Where a power supply system is the main ingredient for a country’s economic growth and quality of life. Nowadays installed transmission capacity for evacuation is an emerging bottleneck, distribution systems are outdated having huge losses are the cause of concern, there is a need to upgrade transmission and distribution infrastructure. The switchgear industry continues to innovate and upgrade its products to meet the evolving/future needs of its customers. From the works of literature, we are identified to analyze the mechanism of the switchgear, where most of the failure takes place due to guiding of helical compression spring in the mechanism. Hence we need to avoid this failure by analysis of spring using analytical, FEA and experimental method. FEA analysis takes place by modeling of spring using PRO-E 4.0 and Meshing and analysis can be done by Ansys 14.5 Software. Experimental stress analysis of spring done by using the universal testing machine with the help of strain gauge mounting on the spring. Results of Analytical and FEA validate with Experimental results.
