MODEL DEVELOPMENT AND THE SHAPE OPTIMIZATION ANALYSIS OF A REAR KNUCKLE FOR RACE CAR

Abstract

Automotive motorsport sector demands lightweight car component that directly contributes to fuel efficiency of a race car. Currently, EIMA Race Car got issues with the car weight. The current knuckle is heavy and did not undergo design process and analysis. The race cars need to compete with others in a 15 laps of endurance race. Refueling is prohibited during the race, thus it is very important to ensure the parts are in top condition and lightweight. By using the selected method and optimization tool for the rear knuckle, this paper looks into the design and development of a knuckle for EIMA race car. Solidworks has been used as a design tool and analysis process. The final design then undergoes an optimization process and the proposed design has been fabricated. The result can be considered successful as the new design is 70% lighter than the current rear knuckle.
