I do have time to analyse it but I was hoping to draw on the knowledge of my engineering forefathers rather than repeat a task already done. As it seems there's relatively little information on it it's sparked some curiosity in me.
I'm a bit confused as to why, but yes - are you considering...
Thanks Ted, that's a really good find. I do wonder if it's considering that for bolt-through use? I know NASA work to stringent standards but if it's the nominal standard that means a certain car manufacturer throws all that to the wind and does what it likes!
Indeed, I'd agree (though that image is a bit limiting in some ways). Hence my wondering if there were established rules for this. I could make a best-guess stab at it but that's not really an engineering solution and on a safety critical part I wanted some theoretical or established backup...
Because while the thread root might be the area that takes the load, but it has to be supported and reacted by surrounding material. Take it to an extreme - if I put the thread so close to the side that the root material was the outer edge, then took it to failure you'd rip out a strip of...
I'm attempting to identify the miniumum material required around an internally threaded hole to maintain thread/material integrity. The advice from the other threads I've read has been to use the AF size of the fastener, however the scenario I'm considering is slightly different and the standard...
And so the ultimate answer here, as far as I can determine, is that the OP and I are best picking a tyre that's cheap and easy to find (while reasonably suitable performance-wise) from those commonly used in normal road vehicles, then just testing them and adjusting the suspension as needs...
@GregLocock - Did you, at an OEM, have to pay to get access to the tyre data or did you simply test and re-define changes in those iterations? At the end of the day I, and the OP to some extent I guess, are trying to get the best data we can to base a design on. What seems to be openly available...
CapriRacer - cheers for your input, always happy to have misconceptions corrected by those in the know. Clearly all the factors are a tradeoff but if you have raw numbers from a standardised test structure you at least have something to go by. However I still don't think there were any...
Indeed, there's pretty much nothing available for non race tyres so it's bordering on pointless, barring a general design strategy. The variation of road tyres from one make to the next in exactly the same sizes is vast and undocumented (I find it somewhat odd that you can't see the precise...
I'm quite interested in this topic myself and I'm in the middle of reading a lot of surrounding literature on the matter (scratch building a lightweight mid-engined spaceframe car with up to 400hp). While looking at the calculations I'm using it is obvious that I need to choose a wheel/tyre...
