Keywords:
Vehicle chassis, Stress, Finite element analysis, Displacement, Strain, Factor of safetyAbstract
This study aims to analyze vehicle frame performance based on finite element analysis (FEA) simulations, evaluate stress distribution, deformation, and safety factors under static and dynamic load conditions, and optimize materials and geometry to reduce mass while maintaining rigidity and safety. The methods include a 3D frame model constructed in CAD software, import into FEA software, full-load bending, sudden braking, turning, and modal analysis simulations. Results show that alternative materials and geometric optimization can reduce mass by approximately 10-20% with stress increase tolerance and natural frequency reduction remaining within safe limits. Conclusion: Material optimization and geometric design are crucial for modern vehicle frames, especially electric vehicles or lightweight frames, to achieve a balance between strength, safety, and efficiency.
