ANALYSIS OF VIBRATION ON MULTI - LEAF SPRING IN AN AUTOMOBILE UNDER LOADING USING FEM TOOL ANSYS

The leaf springs are widely used in suspension system of railway carriages and automobiles. But the form in which it is normally seen is laminated leaf spring . To assure proper spring life, the maintenance and inspection process must include the entire suspension system of springs and chassis parts. The motoring public has learned that proper maintenance on their vehicles is essential to obtain longer life and econ omical service in this age of rising equipment and fuel costs. In most normal maintenance checks, the spring suspension system is sorely overlooked, but a minimum of attention to the spring suspension would yield a longer and more reliable suspension syste m service. In this report,FEM approach has used for predicting the stress and deformation .A parametric study is also made by varying the load to investigate their effect on the stress of leaf spring .A frequency response graph is plotted to analyse the ef fect of Stress, Strain and Deformation.
