Abstract
Abstract: In commercial vehicles, leaf springs play a major role in designing the suspension system. Leaf springs are the most popular designs having multiple leaves in contact with each other and show hysteresis behaviour when loaded and unloaded. The leaf spring acts as a linkage for holding the axle in position and thus separate linkages are not necessary. It makes the construction of the suspension simple and strong. Because the positioning of the axle is carried out by the leaf springs, it is disadvantageous to use soft springs i.e. springs with low spring constant. Leaf springs are excellent in suspending large loads, since they are designed using 'bending beam' equations. The stiffness of the leaf spring assembly can be altered as desired, by changing the number of leaves. The objective of this paper is to compare the bending loads coming at the rear wheel centres of the vehicle when it runs in torture track and over a single bump. Bending loads were
