Leaf spring often experience varying load cycles, significantly impacting a vehicle’s performance. Most suspension system components are susceptible to fatigue failure under different operational conditions. Researchers have made efforts to evaluate the fatigue life cycle of the leaf spring suspension system by using different approaches. However, existing approaches are often complex, time-consuming, not precise, and user-friendly. This research introduces a specialized analytical Design Tool model architecture designed to address these limitations. It facilitates the precise evaluation of fatigue life cycle by establishing the relationship between different standard parameters and user requirements. The tool offers user-friendly solutions for decision-making, incorporating standard parameter, empirical calculations, component sizing, and life cycle estimation.
