Once you’ve tested a couple broad concepts you should be able to get an idea for which tubes are efficiently helping the rigidity, and which tubes are just there and can be omitted or made smaller.

Keep in mind the rules exist for safety, and a level playing field, they are not guidelines for performance I read a neat SAE paper where they compared cornering performance to torsion stiffness. But do not underestimate the task of getting the car done. Lamar County Speedway Shootout. Log in or sign up in seconds. My question is that are the parameters for those tests given?

In reality, that’s not an efficient way to do it. We had that happen to our first car during testing for our desigj car and we were lucky no one got hurt. All opinions are my own and not those of current or previous employers.

They do not say it must withstand a particular amount of load.

Designing an FSAE chassis –

The engine block mass attached to the mounts. I read a neat SAE paper where they compared cornering performance to torsion stiffness.

Was hoping to do AF for our car as we’re at the start of our 2 year build cycle right now. IMO if a first year car can finish and score in all the events then regardless where you finish its a win in itself. 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 Chasis would recommend reading the alternative frame rules section as a learning exercise, but not building to them, as despite the extended design time, you will probably end up with a heavier frame than ‘SES’ rules.

CHASSIS DESIGN (FIRST TIMERS) : FSAE

If you explain to the judges that you’re a first year team, and you’re design is not fsaf refined because of it they won’t frown upon that.

You’ll be much happier having a heavy car that completes all the event, than a “light” one that has the wheels fall off. Submit a new text post. Your due diligence for crash safety is achieved by meeting the chassis rules Torsion stiffness and other parameters are relevant for how your car handles, and for design judging.

Estimate a cornering force, set a target way, FBD your way up from the tires to get the loads, and set a relatively generous safety factor to start so you don’t end up breaking all the time. Personally I think you can do a lot of thinking but without actually put your hands on something you can’t tell where your practical limit is. Issue with one of the dates? Impact is a weird case for fixturing, because in reality the fixture is inertia.

Design and optimization of a Formula SAE racecar chassis and suspension

Grip is a four letter word. Would I need more software support than just Solidworks and its simulation packages? Apply these loads along the correct direction to the correct nodes, and evaluate what your chassis deflections mean for vehicle dynamics.

Adapt as you see fit. I’m used to combustion, so you might have some funky battery things that need frame considerations 4 Connect the dots with rule appropriate tubing. You would find out if the engine mounts break and dump a block in the fsxe back though A more realistic method is fixturing the frame anywhere away from where you are concerned with stress.

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 that all perform an essential function. Tom, quit board posting and go finish Your build blog. Design your suspension first and figure out where the nodes are, then draw the chassis.
