Chassis strength, Static loading, Finite Element Method (FEM)Abstract
This research analyzes the static loading strength of energy efficient car chassis, crucial for the Energy Efficient Car Contest (KMHE), using a quantitative approach based on the Finite Element Method (FEM) via Autodesk Inventor 2024 simulation. The study evaluated two chassis designs (A and B, where B includes additional rollbar supports to enhance rigidity) and three material variations (Allumunium 6061, Carbon fiber, and Titanium). The simulation results indicate that chassis concept B consistently provides superior performance across all tested materials, demonstrating lower stress values (minimum 170.2 MPa with Titanium) and minimal displacement (0.4411 mm with Titanium), signifying a more rigid structure. Although all combinations meet the safety requirement (minimum safety factor > 1 ul, ranging from 1.44 ul to 2.46 ul), the combination of Chassis B and Titanium material is proven to be the most optimal choice, offering the highest structural integrity and minimal deformation.
