Shear Panel 1020 Steel FSAE Tube Chassis

The 2019 FSAE chassis was constructed in attempts to create a lightweight ridged FSAE vehicle while furthering our FSAE club\u27s knowledge of composites. The basic structure of the car follows a typical 1020 mild steel tube chassis design as laid out by the FSAE rules. To maintain a sub 75 lb frame weight while maintaining a torsional rigidity of 700 Lb-ft/Degree. The development, has taken part over the past 6 months. The first 4 months were spent setting design goals, based on the previous year\u27s competitions to determine what it would take to put a car in the top 25. Once the goals where set, the frame was designed with an emphasis on rigidity, ease of manufacturability, and adherence to the rules. The remaining 2 months has been spent physically building the frame, and validating the design through FEA (Finite Element Analysis) and physical testing of various sandwich panel layup designs. All of the testing processes have been meticulously documented to ensure quality repeatable results for future years to reference. The work has culminated with a 69lb FSAE rule compliant Chassis, currently being fully assembled to race in the 2019 FSAE Michigan competition. In final the Composite shear panel will allow the frame to will allow the car to perform better in areas such as maximum cornering force (lateral g\u27s). Better turn in at speed. Finer adjust-ability of the suspension, all while keeping the car light so accelerations and deceleration\u27s will not be affected
