Abstract:

In automobiles like light motor vehicles, heavy duty trucks and in rail systems, Leaf springs are mainly used in suspension systems to absorb shock loads. As an alternative to material of steel spring in this work mechanical behavior of glass fiber reinforced polymer (GFRP) composite mono leaf spring have been investigated. The study of GPRF composite leaf springs has been popular for light weighting in automotive. So, the research on the fatigue life of composite leaf springs is crucial. The important issue now in automobile industries is to reduce the Weight. Weight reduction can be achieved by the introducing of better material, design optimization and manufacturing processes. In this work, all the dimensions of an existing mono steel leaf spring of a Maruti Alto 800 vehicle has to be taken after that modeling and analysis of a laminated composite mono leaf spring with glass fiber composite material has been done. After this we have taken the fatigue life of composite leaf spring by using FEA & results are validating with experimentally.
