For any suspension system, spring is a very important element. In suspension system springs are mainly used for absorbing shock energy as well as restoring the initial position of part upon displacement for initiating the given function. The spring supports weight of the vehicle, maintain ride height and absorb road shocks. Most commonly used springs in suspension systems are Helical coil compression springs. Suspension system springs work on two cycles compression cycle and extension cycle. The compression cycle controls the motion of the vehicles unsprung weight while extension cycle controls heavier sprung weight. The important problem faced by automotive is that the vehicle handling becomes difficult and leads to uncomfortable ride when spring bouncing is uncontrolled.
