MODELING AND ANALYSIS OF LEAF SPRING USING FINITE ELEMENTS METHOD

Leaf spring has a great importance in a modern automobiles industry and it is the main component of the suspension system. It is used in vehicles to absorb vibration and shock. In this paper, the simulation and analysis of leaf spring has been achieved. Leaf springs with two types (multi-leaf spring and parabolic leaf spring) are simulated by using solidworks 2018. The analysis process is achieved by using finite elements analyzer ANSYS 15 with two materials are selected for leaf spring, the conventional steel and carbon composite under two different loads (5000, 10000) N to estimate the total deformation, stress, strain and shear stress. The results showed that the multileaf spring could withstand the load and deformation better than the parabolic leaf spring. The carbon composite is more suitable to manufacture the leaf spring than the conventional steel because of its high strength and light weight.
