Is there any easier way of making tire blow out simulation?

Hi,

I am trying to run a tire blow out simulation. I made some research and it seems the easiest way to use Ftire with inflation pressure around 0 bars.

I got an ftire data with pressures with the tire tests were performed at 8.5 and 10 bars.

I would like to get your opinions about making the analyses with the extrapolation form 8.5 to 10 bars to 0 bars inflation pressures would be realistic or not.

During my research I couldn't find any study with Adams in tire blow out analyses, have you seen any study on tire blow out analyses in Adams? Is there any easier way?

Regards,

Yahya,

Hi Yahya,

yes, FTire can be used for tire blow-out. There are different ways to prescribe the respective inflation pressure time history; please have a look at FTire's docu.

Unfortunately, up to now we do not have respective measurements that can serve as an accuracy indicator. However, from the *physics* point of view, FTire's approach is definitely realistic.

FTire comes with some hardcoded residual internal structural stiffnesses at p=0 (see docu). To start with, I propose to use only *one* of your stiffness values and rely on the interpolation method between this respective stiffness and the residual stiffness.
