What has also been discussed at length is sustained G forces. It is extremely difficult to properly simulate accurate sustained G forces on a dyno, most processes involve heavy use of computer estimations from sim programs to fill in the gaps.Craigy wrote: ↑Thu Dec 06, 2018 5:28 pmWe've been around this discussion before. There are dynoes that can give more than 1G on a gimbal.ian_s wrote: ↑Thu Dec 06, 2018 4:19 pm2G would still give better info than the maximum 1G on a dynoBandit1216 wrote: ↑Thu Dec 06, 2018 8:00 am
Will surely not even be close. I was calculating a bit with some co workers the other day. Rubber to asphalt
friction coefficient is about 1 according to the net. It might be somewhere near 1.3 with a lot of rubber on the track?? Even if you assume 1,5 coefficient and 1,5 down force to weight ratio on the NSX, which are both high assumptions IMO, they can get to 2,25 G. Not even close to F1.
I think G-force is the one thing quite different on track vs dyno though.
This was talked about at length when Honda discovered issues with their 2017 oil tank design on the track that were not seen on the dyno which was followed by a lengthy discussion about computer simulation and replicating accurate fluid slosh dynamics and the challenges involved with that..
