Design and Analysis of the Suspension Upright Structure of a Formula SAE CCar

Abstract

The suspension system is one of the most important parts of a vehicle. It plays an important role
in the absorptions of shocks and impacts. It also determines the safety and rigidity of the rear and
front arm connection of vehicle. The objective of this study was to design a new suspension system
for a Formula SAE Competition. The scope and parameters are identified with the selection of a
racing car wheel and tires and availability of current resources from previous research projects
such as car chassis and lower and upper double A-arm. The upright structure was designed in
certain steps to reduce weight by minimizing the surface area at the same time by considering the
strength of the material. Results showed that the geometry with the lowest stress is at 8.037 MPa
with a length of 220 mm and width of 120 mm. The simulation provided a concrete data of how
the structure behave with different dimensions but also the most critical point is attaining the
equivalent stress of the designed structure. For future studies, improvements can be done by
changing the parameters and conduct experimental method to see any deviations from the
theoretical/simulation results.
