Design Improvement and Structural Analysis of the Chassis-Body for a FuelEfficient Eco-Vehicle

This paper presents a study on the structural redesign of the chassis-body system for a fuel-efficient eco-vehicle using CATIA software. The objective was to optimize the frame structure to meet key design criteria, including minimal mass and aerodynamic efficiency. As a result, a new configuration was developed that ensures high dimensional accuracy, reduces overall weight, and lowers the vehicle's center of gravity. The proposed structure features a simplified design that maintains essential strength and stiffness characteristics while supporting aerodynamic performance, making it suitable for application in energy-efficient vehicle competitions.
