Alloy chassis design info needed
No, its NOT that same old question again.
I am looking for detailed design information on alloy chassis cars, but not alloy tube spaceframes.
Mainly I am looking for photos, drawings, descriptions etc of the Elise chassis and Morgan Aero 8 chassis.
Particularly extrusion pictures, fabrication pictures, bonding, riveting, welding details.
Doing the usual 'google search' gets some very basic info which I now already have, but are there any really good technical documents on
line that I may have missed?
Or any books on the design of such cars?
I do have several books on chassis design, but if there are any good recomendations then please let me know.
I'm not after suggestions of designs, or what I should or shouldn't be doing as I've seen so many of those threads. Really I'm
just looking into research thats already been done on the subject and the Elise is obviously a prime example.
Locost? Definitly not.
Thanks,
Steve.

have you seen the sterile conditions required for bonding the lotus chassis together? how do you repair a car like that?

Nope, do you have photos of it then? As thats the sort of info I need but can't find

I've seen a repair of a Harrier wing being done. Was at one point the largest composite wing in the world. I never thought it would be possible
to repair it.
But the repair of this chassis is not something I need to consider just yet. That is months later in the development.

Not sure how technical this would be.
Did a quick search through my Uni library, not much came up that was up to date, will post the search results if interested.

Some details of the Elise chassis in this shot. Can see the red adhesive quite clearly.
Some pictures of a morgan chassis (the aluminium car, which I suspect shared most of the chassis) are here:

Finally some Audi R8 cad renderings of the chassis are buried in this lot

I'm sue the latter pictures of the morgan chassis are from our labs where some students where doing the control system for the electric drive,
should take a look and see if its still there!

Yeah, and so have my Dad and his work colleagues, who laughed quite heartily at them.
If the commercial passenger aircraft they work on all day can be glued together in drafty, dusty and dirty old hangers, so can a car.
I wish I could remember his colleagues parting comment on the situation, something about anal, moronic and laughable.

Have you looked through this website?
http://www.sandsmuseum.com/cars/elise/thecar/chassis/index.html
Plenty of good information on there but you have to trawl the links to the interviews and various subsections to piece it all together... Well worth a
read though!

quote from above website -
The bonds were executed in a controlled environment with careful monitoring of temperature and humidity to ensure every bond was perfect, before the
rivets could be applied and the structure removed from the jig for the adhesive to be oven-cured.
oven cured...

Some info I have seen, but some I hadn't.
So, thanks very much guys, all very much appreciated. 
Anyone have that Lotus book by John Tipler? Is it a good read?

The "motorcycle engine race car" book that people were talking about on here a couple of months back has a section on chassis construction
and within that there is a sub-section on aluminium honeycomb monococques. It is aimed at the single seater but has a bit of good info. sorry I
can't remember the proper name of the book as it is at home under the bed!

If I remember right, Prepare to Win bay Carol Smith has quite a lot on rivited aluminium monocoques. It's a good book anyway.
I would have thought that the combination of riveting and bonding would be a good approach.
If you do a google for aircraft design, you should come up with lots that is of use. eg:

If you contact the open university part of one of there course towards an MSc in Manufacturing: Management and Technology contains a unit dedicated
to the design of the chassie on the audi A6. I dont have mine its been a few years since i did it! but im sure if you go down to your local office of
the OU thay would let you read/borrow it!
