SIMULATION FOR OPTIMIZED MODELLING OF EN45A LEAF SPRING (original) (raw)

Simulation using CAE tools have been performed using three different models of leaf spring to find out an optimized model considering design and material optimization. To optimise the EN45A leaf spring assembly the conventional flat profile has been changed to parabolic one. In which the thickness of the leaves decreases from centre to edges. This change in design results into elimination of interleaf friction of the mating leaves. For material optimization the material of leaf spring has been replaced from steel (EN45A) to composite materials (GRP). The objective of this work is to produce an optimise model of leaf spring with reduced weight, stresses and improved fatigue life for similar loading conditions.
