COMPARATIVE STUDY OF SINGLE LEAVE LEAF SPRING IN CAE TOOL AND EXPERIMENTAL DATA OF LEAF SPRINGS IN AUTOMOTIVE VEHICLES

The work is carried out on the front end leaf spring of a commercial vehicle. The objective of this work is to Carry out computer aided design and analysis of a elliptical single leave leaf spring, with experimental design considerations and loading conditions. The material of the single leave leaf spring is 65Si7.The CAD model of the single leave leaf spring is prepared in Solid-Works and analyzed using ANSYS-14.0. The CAE analysis of the single leave leaf spring is performed for the deflection and stresses under defined loading conditions, using ANSYS-14.0. The experimental and CAE results are compared for validation. Using CAE tools the ideal type of contact and meshing element is determined in leaf spring model.
