Abstracts: Parabolic leaf springs are essential suspension elements used on mini loader trucks necessary to minimize the vertical vibration, impacts and bumps due to road irregularities and to ensure safety of the loaded cargo. The new innovative design is characterized by the use of less leaves whose thickness varies from the center to the outer side following a parabolic pattern. The parabolic leaf spring absorbs the vertical vibration and impacts due to road irregularities by means of variations in the spring deflection so that the potential energy is stored in spring as strain energy and then gradually released to maintain comfort. The mathematical equation between the thickness & the length of the spring is that of a parabolic leaf spring. This results in less inter leaf friction, because of which the only contact point between the springs in vehicle is at the end and the center where the axle is connected. Modified version of leaf springs is the parabolic leaf springs for automobiles and has better load bearing capacity with less weight. In our present project we will be designing a parabolic leaf spring & manufacturing with the experimental analysis. We will do stress analysis and could redesign or replaced this leaf spring with conventional leaf spring and compared the result. The main objective of the project is to design and modify the current heavy suspension system with the light weight system which can save the material as well as product cost.
