Abstract:

The rising popularity of electric vehicle (EV) have imposed an increasing interest in development for efficient and effective vehicle chassis designs. Utilizing the concept of shared platform can lower the price of a car as shown done with many car manufacturers. However, not all chassis designs are able to accommodate the unique demands of an electric vehicle powertrain. A further study on structural analysis and optimization for electric vehicle’s chassis design is required. The objective of this study is analysing the feasibility of a conventional ladder frame chassis to accommodate an EV powertrain with minimal modifications. A 1994 Chevrolet K1500 chassis serves as reference, using finite element method (FEM) with computer aided design (CAD) software, to assess the structural integrity of both original and modified designs. The modifications were found to be minor, with just the removal of the middle crossmembers and strengthening the side rails where the battery will be mounted. Simulations show an increase in factor of safety value by 2.23, demonstrating improved structural integrity. Additionally, the estimated range of the vehicle is 270km, proving the potential of ladder frame adaptation for EV.
