DESIGN AND ANALYSIS OF COMPOSITE LEAF SPRING UNDER STATIC LOADING

In modern vehicles it is necessary to reduce weight and increase strength of each component in order to attain a good travel range, for e.g., in electric vehicles (EV) the mileage is greatly reduced by the weight of powering batteries (>10% of total vehicle weight). The more the weight on a vehicle, the more work there is to be done for suspension system and consequently less comfort for the passenger. To solve this problem the suspension system needs modification both in terms of geometry and material of the suspension. Therefore, for the required changes from the proven history of leaf springs, they can be considered, and leaf springs have good load bearing capacity and can provide less deflection for high loads resulting in a comfortable ride. In this article, semi elliptical laminated type leaf spring is considered as case study model which is designed in SOLIDWORKS 2020 and the static structural analysis was carried out over it in ANSYS Workbench 19.2 software to predict the behaviour of leaf springs.
