Formula Sae Rear Suspension Design

Abstract

The purpose of this report is to investigate the design development and evaluate the structural and functional performance of the proposed system for the 2019 competition. With the review of the literature surrounding rear suspension systems, FSAE standards, analysis techniques and important design parameters, the foundation for the proposed James Cook University (JCU) 2019 rear suspension system is established. This paper is highlighted the development and analysis path undertaken in the construction of rear suspension system befitting a Formula SAE vehicle. Formula SAE is an international student competition centered on the design, construction and racing of an internal combustion vehicle. All parts are designed via SolidWorks and FEA testing is incorporated using ANSYS to test out various loads under different scenarios in racing. Main components including beam axle, trailing arms, brackets, spring and damper are covered in this paper. The design is focused on providing a low cost and easy to manufacture design which operate for infinite life cycles.

Quantitative Methods for Steering Knuckle Material Selection

“…Most passenger cars and light trucks are equipped with an independent suspension system on the front axle, as it provides significantly more space for the engine mounting, greater wheel movement, increased vibration resistance, better vehicle handling, and overall better driving comfort. The disadvantage of this system is the complexity of the construction and high production costs, due to the increased number of parts [8,9]. There are several designs of independent suspension system, of which the most widely used is the system with two control arms of different lengths (Double Wishbone Independent Suspension), shown in Figure 1.…”
