Suggestions for a book for off road buggy chassis design
(OP)
Hi we are looking at entering off road racing and would like to build a small lightweight 2 seater buggy. < 1330cc / 750cc turbo.
Does anyone have a good recommendation for a book on chassis/suspension design.
Thanks
Dave

I ordered Engineer to win, I guess that's the one you meant and have signed up for FSAE - there is some reading to be done there, should keep me off the streets for a while.

Off road suspension very much involves maximising travel and dampers.

There was a time when Reynolds 531 ( broadly similar properties to 4130) was joined routinely by bronze welding, but was tricky to TIG weld
RE: Suggestions for a book for off road buggy chassis design
His concern stated in this edition was the indiscrimate use of 4130 as he said "Unfortunately, chromemoly steel has become trick" in vogue or fashionable, apparently having observed people using it as he said "a little bit of knowledge is dangerous".
His concerns were multiple, particularly in roll cage construction, wanting a metal that will bend, rather than break.. with breaks being far more hazardous to the occupant. His comment "Under crash impact, a chrome moly steel part is much more likely to break rather than bend, as would a mild steel part".
I know in the off road, 4x4 market there have been some aftermarket chromemoly suspension parts fracturing due to improper or no stress relieving after welding.

2 - permanent bending due to brief torsional or bending overload - 4130 wins ( 10% bigger diameter of lesser material buys LOTS more strength and stiffness, if that's what I want)
3 - fatigue failure due to repetitive loading - 4130 wins the brochure race, but tiny geometry details inadvertently done poorly will absolutely murder either material
4 - potential for local brittleness from too rapid cooling after welding, especially TIG or MIG - 41XX loses - potentially made FAR worse by the geometry similar to item 3
RE: Suggestions for a book for off road buggy chassis design
I'd favour cromo for the suspension arms, and build them big, and then something a bit better than the nastiest mild steel for the frame. This has been discussed several times, use the search engine.

RE: Suggestions for a book for off road buggy chassis design
There's more to it than working out forces and cross-sectional area to determine stress and therefore material strength.
It's called design.
RE: Suggestions for a book for off road buggy chassis design
Maximising strength where cracks or bending start while reducing weight where they don't is the key. Intelligent design and use of the correct material for each part is important.
Regular inspection and maintenance is also important, and reducing weight at the expense of durability is acceptable on non critical, non safety and easily replaced parts as by doing that we reduce the load on important suspension parts.
