Modificación Del Sistema De Suspensión Del Renault Clio Mediante Simulación En Inspire Motion Para Competencia De Rally

Abstract

The main goal of this research is to improve the suspension system of a Renault Clio II for rally competitions, following the current FIA rules. Rally races have many different road conditions, so the study focused on making the car more stable and easier to control. A quantitative method was used to collect and analyze technical data from the suspension system. The main parts studied were the geometry, shock absorbers, and springs. The purpose was to measure how much the changes affected the system’s behavior. The most important change was using two coil springs with different spring rates (84 N/mm and 65 N/mm), creating a double spring setup. Also, the normal shock absorbers were replaced with competition ones. To test the system, the software Inspire Motion from Altair One was used. The program helped simulate how the suspension worked, and results from the original and modified systems were compared. The simulations showed that the changes made the car adapt better to different terrain types, which improved performance in difficult conditions. In conclusion, the new suspension system gave the Renault Clio II better control and performance for rally competitions.
