Single Seater Frames

[flynfrog]

Absolutely everything you need to know about single seater spaceframe construction. Read it. Study it in depth. After devoting time and study, gaining a basis of knowledge that will allow you to ask questions based on expertise. Use search engines. A massive amount of material is available to anyone willing to do the work. This is a starting point. After study return with questions based on expertise. Your questions are so general they will lead to 200 pages on the Forum. Do the work. Research the FIT threads, a wealth of design information and recommended texts specifically on spaceframe construction is on the F1Technical Forum. Contact the author of the link below. Race Car Engineering/ss collins have run multiple articles on FSAE and space frame formulas. The text referred to in this dissertation, on spaceframe construction > Racing & Sports Car Chassis Design by M Costin can be bought on the internet for as little as 6USD or a pristine copy for 2400USD. Search for it. Buy it.

Formula SAE-A Space Frame Chassis Design Dissertatioin by Christopher Scott Baker, University of Southern Queensland, 2004
116 pages
http://eprints.usq.edu.au/39/1/christop ... R-2004.pdf
Everything you need including structural anaylsis with formula from M Costin book included in the above PDF

This site features a series of pictures under "Construction" showing the entire procedure of building a complete chassis jig/bench then building/welding a space frame chassis from begining to end.

Now build your spaceframe chassis

Just do it
EDIT - The last GP/Formula 1 spaceframe chassis were built from - " Twenty five ton mild steel is quite suitable for welded tubular structures of the space frame type, but some manufacturers use a material which approximates to aircraft T45 specification, a maganese steel alloy which is particularly suitable for welding" - M Costin - The "Cos" in
Cosworth.

I would say that SAE chassis is a relatively poor design in placement of suspension nodes and the lack of triangulation between the front and rear hoops

FSAE spaceframe chassis with excellent triangulation at suspension nodes.

"Front frame and suspension during construction. Tubes are 1 x .028" 4130 steel; joints are TIG welded." David Malicky


@flynfrog
It all depends on the chassis designer and the specifications of a formula or classification. There is a wealth of design information available including pictures and diagrams of many different spaceframes on the internet and many books available; it's well worth researching before designing or building a chassis. It's not for me to defend FASE chassis...there are thousands of students and engineers and the SAE to do that

Which spaceframes would you recommend as good examples of design?
The Matra and Porsche prototype's spaceframe chassis are well worth a look. Anyone else have favourite examples?

"The big lessons from the FSAE project were 1) creative mechanical design is tremendous fun to me and 2) exchange and development of ideas in a team setting is highly rewarding and results in a better design.In retrospect we triangulated the '88 car in excess, as the car was not mass-produceable. And it takes a very long time to TIG weld all those .028" wall joints. But we did achieve 3200 ft-lb/deg at only 33 lb frame weight, which is respectable even today." David Malicky


Quite an accomplished engineer with an interesting career. His homepage says he is always willing to talk about engineering...here is his link.

here is our chassis not the end all of chassis but we didn't leave the nodes hanging out in the middle of tubes either

Flynfrog that looks very similar to our MiniBaja chassis.
