Analysis of Mono Leaf Spring using Photoelastic Technique and Finite Element Approach

Abstract

This study focuses on the stress analysis of a Mono Leaf Spring for a Mahindra Jeep using Finite Element Analysis (FEA) and experimental methods, incorporating photoelasticity for validation. The results indicate that the FEA-predicted maximum stress of 495.21 MPa closely aligns with analytical calculations of 478.81 MPa, confirming accuracy. Equivalent elastic strain and deformation values also show minimal deviation. Stress concentration increases with applied load, and photoelastic tests validate safety under 1 kN loading. The methodology is experimentally validated, ensuring reliability in automotive suspension system design. This approach provides a robust framework for enhancing durability, performance, and safety in leaf springs and similar automotive components. The study establishes a reliable procedure for stress evaluation and structural optimization, offering insights into lightweight, high-performance suspension design. The proposed methodology can be adapted for other automotive applications, contributing to improved load-bearing efficiency and vehicle dynamics.
