The goal of this design project is to design, analyze, and manufacture a chassis for the University of Delaware FSAE team. Through extensive. Designing and constructing a chassis and suspension system for a Formula SAE racecar is a highly complex task involving the interaction of hundreds of parts. PDF | On Oct 25, , Lucas Iensen Bortoluzzi and others published Formula SAE Chassis Design to Improve Suspension Tuning.

Just will fhassis be competitive or easy to drive. You’ll be much happier having a heavy car that completes all the event, than a “light” one that has the wheels fall off. Show full item metadata. Hello again, I just wanna ask another question about assumptions regarding stress analysis. The harder part is what concerns me, structural rigidity.
The ‘most complete’ method would be adding masses to their mounts, and using inertial relief. Or would your normal FEA software just chssis Also slightly less embarrassing. As mentioned previously, a lot of the nodes on the chassis are “pre-designed” by placement of the major components. Building other systems around arbitrary frame points is a recipe for disaster.
Additionally, many of the tube cross-sections are specified in the rules, so there is not a whole lot left for optimization, other than how you “connect the dots. Massachusetts Institute of Technology.
Make sure the driver can reach everything and their helmet is inside the roll hoops. I almost lost two days of work last year, and we recovered the data in less than one hour ddesign to the automatic copies. If your frame is a wet noodle, but still meets the rules, you can drive in endurance.
But that’s probably the easier part. There are justifiable arguments for both paths. They do not say it must withstand a particular amount of load. After that, find nodes where tubes will meet, make sure they’re triangulated properly, and remember to have tubes where you want the suspension pickup points! Also would recommend a seperate suspension tab jig There will cyassis iterative design around suspension, engine mounts, and driver position.

CHASSIS DESIGN (FIRST TIMERS) : FSAE
Is the chassis significantly more stiff in torsion than the suspension roll stiffnesses? They might have recommended design practices, or other very useful tips. Keep in mind the rules exist for safety, and a level playing field, they are not guidelines for performance.
Yes, we are a rookie team, my school tried building ones in the past but never really worked out, I plan on getting the wheel going with this so fingers crossed. A lot of it should be literally connecting the dots, and keeping tubes where the sfae allow. As others said, connect the dots, and read the rules.
Design and optimization of a Formula SAE racecar chassis and suspension
You are not designing to any crash loading cases. I’m leaving composites out of the picture for now, I have to work with the steel tubes we have in our lab.
The reverse can also be successful – design with ultimate reliability as primary and loss of performance as the risk, then reiterate to improve performance using analysis FMEA can be used since extreme lack of performance is a “failure mode” of a race car There’s nothing easier than over-designing the chassis and making it weigh a tonne, but that’s not my goal, not on a race car at least.
Join Our Discord Desing Post here to have your team added to the wiki. Most FSAE teams choose the latter but often lack the scientific approach of what to improve.
Designing an FSAE chassis –
Development blog Features Glossary. You’re right in that a good chassis makes for a good starting point. Only then can you begin to make Chassis. You must must must start with the driver feae.
My question is that are the parameters for those tests given? Try to build the CAD model so that changes can be made. What sorts of loading do I need to apply to the chassis to mimic real track stresses?
