The_Wodge Posted February 25, 2008 Report Share Posted February 25, 2008 Having built and tuned more engines than I can count, I'm being asked more and more about chassis tuning too. I touched on it a bit when I was at uni, but nothing really in depth. Does anyone have any good recommendations for books which cover the technical side of things like tyre choices, spring & damper rates etc etc. Ideally it would involve data loggers/accelerometers and how to use these to best advantage. Any top tips would be most welcome! Cheers, Paul Quote Link to comment Share on other sites More sharing options...

Sam@TDi Posted February 25, 2008 Report Share Posted February 25, 2008 Indeed welcome to WIM Personally I've found it extremely difficult to gain access to good quality scientific information on the subject of vehicle dynamics. I'm my opinion the academic land scape in this field is clogged with authors offering their opinions often passing them off as fact or worse still preaching as an expert based solely on their own trail and error experience without any real understanding of the true mechanisms at play. I would recommend that you cast a skeptical eye over as much material as possible, then perhaps mentally attempt to sort the wheat from the worryingly large amount of chaff. I've been lucky enough to work with some talented people in this area and I've certainly gleaned far more from my discussions with these people then from any of the books I've ever read on the subject.

Tony Posted February 26, 2008 Report Share Posted February 26, 2008 Welcome to wim I have to agree with Sam... I found most of the information dated or type specific, in fact that's one of the reasons i built wim. Saying that though snippets of information from books like "suspension bible" construct an overview so long as their not considered law, our market place is constantly evolving. On a brighter note Geometry is global so once any student understands the figures are also forces then the need is only to understand what force and how this interacts dynamically. Personally i think Geometry is simple compared to suspension dynamics.... don't even think about aerodynamics Quote Link to comment Share on other sites More sharing options...
The_Wodge Posted February 26, 2008 Author Report Share Posted February 26, 2008 Thanks for the welcome. I fully subscribe to the approach of working out what forces are present then going from there. I also agree that there is a lot of tosh written- I run a flow bench as part of my engine building and a lot of claims of other people/books/papers etc are exactly that- claims! An industrial background in fluid flow helps to quikly sort out those who are talking rubbish! However, a good start is to get an understanding- even if it is wrong as the best education will be to disprove this. The only way to learn is to make mistakes, but hopefully they're not costly Thanks chaps, Paul Quote Link to comment Share on other sites More sharing options...
Tony Posted February 26, 2008 Report Share Posted February 26, 2008 Absolutely..... In truth the field is to wide to be encompassed in any book...

TDIPLC Posted February 28, 2008 Report Share Posted February 28, 2008 It may be worth reviewing the SAE library. SAE is a world authority on all automotive issues, and the white papers that are published are reviewed by the leading scientists in each field. I gleaned much of my knowledge of engine dynamics from SAE white papers. It's a very deep mine of authenticated scientific data. Quote Link to comment Share on other sites More sharing options...
