He seems to do the simplest approximation of curves as constant radius & calculating the centripetal acceleration. That would give you the elementary lateral load on your wheel.The best few hours work I ever did in this project was to set up a simple lapsim to see how longitudinal and lateral accelerations affect laptimes, (i.e. taking the level 2 vehicle performance outputs, and seeing how they affect level 3 pointscoring). The first lapsim I did was really simple – breaking up an autocross/endurance trackmap into a series of straight lines and circular arcs, assigning appropriate lateral and longitudinal accelerations (assuming constant accel), and then finding laptimes. Change acceleration values, see change in outcome. Although very simple, it was one step up from simple “more power:weight ratio is better” reasoning, and gave some really useful results. For example, according to this simple autocross/endurance lapsim:
- A 10% increase in lateral acceleration gives approximately 8 times the points return of a 10% increase in forward acceleration.
- A 10% increase in lateral acceleration gives approximately 14 times the points return of a 10% increase in braking deceleration
(I have no concern sharing these figures, because people like Pat Clarke or Claude Rouelle aren’t going to believe you unless you can prove it yourself. Or come up with your own lapsims that disprove me. Just do it).
I came on here to ask about waterproofing. I think we're fairly well covered but it's amazing where water (and presumably air, which can't be good for drag) gets in. We'll tape it all up best we can, but anyone have any particular warnings/suggestions?Waterproof ? nathing is waterproof in the world of automotive and racing.So make sure any water getting in will be forced to go out and not collect where you don´t need it.greenpower dude reloaded wrote:Heading over to Silverstone tomorrow for our first proper event of the year. It doesn't really count for anything other than pride so we're going along with a view of an extended test. Typically our events are 1.5hours on 4 batteries, and this one is 4 hours on 6 of the same type of battery.
Whilst we have proved we now have a front running car we're going to just take it nice and easy whilst perhaps others will push too hard in what looks to be torrential rain.
As nice as it is to win, now that we've won the national final I kind of feel we have that objective ticked off. There is no doubt that I want to improve our performance but * cliché alert * at the end of the day, you have to step back and think about why we do this. We race in this particular series primarily to learn but also to have fun. If you take one away from the other there is no incentive to continue.
I know that one day I'll find myself as part of a professional outfit and in that situation I'm more than happy to push for victory all the time, in fact, that genuinely is my goal.
Anyway, I didn't just come on here to spill our race strategy
This may sound a bit abrupt, but here comes .. winning one big race does not crown you king. Nothing is ever to be presumed. No position above the fray is granted nor is it permanent. The best you can do is to continue to embrace the same efforts and fire that got you the big win every time you take to the track. Good luck!greenpower dude reloaded wrote:Heading over to Silverstone tomorrow for our first proper event of the year.
