Abstract:
The paper concentrates on generating maximum tire grip by using the frequency response system of individual automobile components.Tire data has been consulted for and used to verify the findings presented in this paper. The tire data has been provided by the FSAE Tire Test Consortium (TTC) & Calspan Tire Research Facility (TIRF), U.S.A. specifically for FSAE/FS teams.Tire parameters such as vertical load, tire temperature, tire pressure, etc. have been given highest weightage as they directly affect the major force outputs in addition to frequency excitement.Suspension geometry design and its role as a precursor to an effective shock absorbing setup have been highlighted here.The damping has been calculated and algorithms related to it have been presented here since effective and quick response of the vehicle's behaviour can be modified through this.Frequency algorithms have been generated after crosschecking with tire data that aim at maximizing tire grip.The base automobile used here is a Formula Student vehicle built as per the 2011 rules and regulations.
