Springs are mainly used as members absorbing shock energy as well as for restoring the initial position of a part upon displacement for initiating a given function. Compression springs are helical coil springs that resist a compressive force applied axially.Compression springs may be cylindrical, conical, tapered, concave or convex in shape. Consider the life of a race car nearly 10 years then the valve spring present in the car engine should withstand cyclic loading approximately infinite number of times.It has been reported by the warranty/ maintenance department that frequent complaints are being received over the failures of these springs well within their intended life span.For a high speed car, the failure of valve spring on any of the cylinder may result in sudden depreciation of the engine power and consequently may lead to threat of life and property due to a potential accident.Hence the spring must be designed for reliability and to withstand the cyclic loading during operation over its life time.Therefore in this dissertation work, it is proposed to carry out the design and fatigue analysis of compression spring used in the engine valve of high speed (racing car) so as to ensure minimum fatigue life of the spring.
