Abstract
One of the vital parts during the design of an automobile is the Suspension system. The primary function of the suspension system is to minimize the transmission of road shocks. The role of composites in weight reduction and fuel saving in automobiles is highly significant. A combination of better material and better design approach will further enhance the weight reduction process. In the present work, multi leaf steel spring is replaced by the optimally designed composite mono leaf spring. A mono composite leaf Spring of unidirectional glass fiber reinforced plastic with similar mechanical and geometrical properties to the multi leaf steel spring, was fabricated and tested for static strength. The objective was to obtain a spring with minimum weight that is capable of carrying external forces without failure. Compare to steel springs, the composite spring has stresses that are much lower, the natural frequency is higher and the spring weight is reduced considerably.
