        abstract = {This paper presents an integrated finite element analysis (FEA) study of ladder-type chassis frames for both on-highway commercial and off-highway military vehicle applications. A comprehensive simulation framework incorporating static structural, modal (free vibration), and harmonic response analyses is developed to evaluate structural performance under realistic operating conditions. For the off-highway (military-type) chassis, global stiffness characteristics, load transfer mechanisms, and structural integrity are assessed under full payload and gravitational loading. For the on-highway commercial chassis, resonance behaviour, vibration amplification, and fatigue life are investigated as root causes of real-world field failures near the leaf-spring mounting regions. Material comparison between conventional Structural Steel and high-strength A710 Steel shows that A710 Steel delivers approximately 20% lower deformation and stress, shifts natural frequencies away from the engine operating range, reduces harmonic deformation amplitude by up to 80%, and improves fatigue life by 94-177% at critical locations. Analytical validation using Dunkerley's and Rayleigh's methods confirms model accuracy within 3%. The study establishes that a combined static-modal-harmonic FEA framework is essential for reliable chassis durability assessment.},
