Designing Shell Eco Marathon Car Bodies with Solid Work

Abstract

The Shell Eco Marathon is a world-class car competition for students. Through this competition, students compete to create innovation and creativity in the development of vehicle technology. The final result of this competition is the birth of vehicles that are economical, environmentally friendly, including a lightweight and aerodynamic body. This study aims to produce an urban concept car body design for racing purposes, with several provisions that comply with the Shell Eco Marathon competition regulations, have a low drag coefficient and turbulence value. This research includes research and development (R&D), using the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The test object is the 3D urban concept body shape design. The development of the urban concept body design uses the Solid work 2018 software with a flow simulation feature to analyze 3D urban concept body shape designs. The results of this research and development are (1) the design of the car body shape has met the competition regulations, (2) the drag coefficient value can be achieved at 0.1965, and (3) the value of turbulence intensity can be achieved at 0.133%. The results showed that the development of the urban concept body shape design was as planned.
