Literature review on Design, Analysis and Fatigue Life of a Mechanical Spring

In this paper are reviewed some papers on the design and analysis of spring performance and fatigue life prediction of spring. There is also the analysis of failure in spring. The aim of this paper is to represent a general study on the analysis of spring. Compression springs are commonly used in the I.C. Engine valves, 2 wheeler horn & many more and they are subjected to number of stress cycles leading to fatigue failure. A lot of research has been done for improving the performance of spring. Now the automobile industry has shown interest in the replacement of steel spring with composite spring. In general, it is found that fiberglass material has better strength characteristic and are lighter in weight as compare to steel for spring. We can reduce product development cost and time while improving the safety, comfort and durability of the vehicles produce. The CAE tool has where much of the design verification is now done using computer simulation rather than physical prototype testing.
