ring loads.
The hill-climbing test provided favorable results. Under tensile-compressive
loading conditions, the maximum stress and displacement (5.36 mm) remained below their
respective thresholds. This confirms that the current chassis configuration is structurally
certified for uphill driving scenarios, offering both strength and durability.

Based on the evaluation of all test conditions, it is concluded that the current chassis
design is stable enough for normal bending and slope-climbing scenarios but requires
reinforcement to withstand torsional and high-speed cornering forces. As a proposed
solution, the study recommends replacing the material of the components that experience
maximum yield strength and highest stress with S420 steel, which has a higher yield
strength than S355. This enhancement is expected to raise the allowable stress limit and
ensure the frame maintains structural integrity across all operating conditions.
Overall, the study demonstrates the importance of scenario-based simulation in
automotive chassis design and highlights the necessity of targeted material upgrades to
achieve safety, durability, and performance standards in modern vehicle engineering.
