| ABSTRACT |
|
Tire contour design theory has always been studied because of its significant effect on tire performance. Based
on the new non-natural equilibrium contour theory, the influence of belt pressure share ratio on the carcass contour is studied.
The type of 385 / 65R22.5 all-steel radial tire was chosen as the research object and the finite element analysis technique was
adopted to calculate the belt pressure share ratio. The results show that with the increase of the belt pressure share ratio, the
clamping effect of belt layer on the carcass is strengthened, the curvature of tire crown in carcass contour increases and the
crown curve tends to be rounded. The influence of belt pressure share ratio on wear, footprint, rolling resistance and grip
performance was also explored with the finite element technology. It turned out that with the increase of the belt pressure
share ratio, the tire wear increased, rolling resistance reduced, grip performance enhanced. |
