Redesigning the existing leaf spring design and analyzing it’s transformation from multileaf to progressive leaf using the finite element method is the focus of this research. The study aims to investigate the impact of these leaf springs when applied to the Mitsubishi L300. The primary objectives include understanding the stress influence, stiffness effects, and fatigue characteristics of both types of leaf springs. Simulation results indicate that the multileaf leaf spring design exhibits a stress value of 503.32 MPa, where Is the progressive leaf spring shows a stress value of 421.98 MPa. These findings suggest that the progressive leaf spring design efficiently distributes loads, thereby reducing potential damage. Regarding stiffness, the multileaf leaf spring design records a stiffness of 6,320 N/mm, whereas the progressive leaf spring exhibits a stiffness of 5,028 N/mm. Additionally, the fatigue life of the multileaf leaf spring is approximately 4.1 years, whereas the progressive leaf spring reaches 6.8 years. Based on these results, it can be concluded that the progressive leaf spring outperforms the multileaf leaf spring in reducing stress and extending fatigue life, despite having lower stiffness values.
