SHELL-ECO-MARATHON

I am currently the leader of the SHELL-ECO MARATHON competition team. This competition involves designing an electric car to maximize the performance of the single-seater. The focus is on reducing the weight of the chassis, selecting appropriate materials, designing the body to minimize air friction, and considering other elements for efficiency optimization. The Shell Eco-marathon is a global event with competitions in the United Kingdom, France, the Netherlands, Japan, and the United States.

As a leader, I am involved in all areas of team creation, and I'll explain my contributions in each area.

Chassis:
My role involves attending, listening, contributing, and conveying information in team meetings. I assist team members in the design and validation of the chassis through simulation and mathematical calculations, using stress and deformation analysis. We successfully created a lightweight chassis using only 14 meters of tube capable of withstanding a yield strength of 240 Mpa. Considering our budget and capabilities, we opted for Aluminum 6061-T6 as the material, providing the required strength and lightweight construction to enhance the race car's efficiency.

Steering and Brakes:
Managing this area as a leader presented challenges, and my approach included personal discussions with the team member responsible. However, when this proved ineffective, I took a hands-on approach and coordinated the area myself. We initiated a comprehensive reading of the rulebook by all team members to identify key aspects related to braking and steering. Setting objectives based on our limitations, we focused on reducing the wheelbase distance to minimize weight. Selecting 20-inch track front wheels within budget constraints, we aimed for a turning radius of less than 8 meters, achieving an angle of 11 degrees and a turning radius of 7 meters for safety.

Aerodynamics and Bodywork:
This area has achieved significant progress. We began by selecting different NACA airfoils, evaluating their values and using Fusion360 to mold a water drop shape with suitable downforce values. With the chassis completed, we modified this water drop shape to fit the chassis, recognizing that slight modifications greatly impact performance. Ongoing flow simulations aim to determine the optimal shape for the race car, which will be constructed using Carbon Fiber.

Finances and Marketing:
Given the school's limited financial support, I established two areas focused on securing sponsors and funds for the racecar's development. Efforts to create compelling content for recognition have attracted sponsors providing support in software courses, materials, discounts, and exposure for the students involved in this project.
