“Analysis & Optimization of Multi-Leaf Spring of Small Segments by Using Composite Materials”

Mechanical Engineering

Leaf Spring Suspension System is used in every automobile vehicle Fuel efficiency is an important factor for running the vehicle. To impact the vehicle to be more economical in terms of fuel, the weight of the vehicle to be reduced by reducing component weight. So, out of many components, one of the components of the automobile, the leaf spring which uses for carried out the whole weight of the vehicle is the best option for the replacement of steel material with composite material. The materials selected for leaf spring are E-glass/epoxy, Carbon epoxy, and Graphite epoxy composite material which is more economical with similar mechanical and geometrical properties to the steel leaf spring. The leaf Spring is designed using both the materials of steel and composites for the same set of loads. The Simulation is prepared for both the models and the FEA test is done showing the stress and detection analysis of Steel and Composite leaf Spring. The springs are tested experimentally by tension and bending test and validating its results with the simulation results. A Comparative study is been made for both the materials, showing the difference in dimensions, stresses, and deflections.
