| Abstract: |
| The application of aramid fibers in belt ply and cap ply of radial tire were studied with finite element analysis software Abaqus.The results showed that，with aramid fibers in the belt ply，the axial stress in the first and second belt ply，circumferential stress in the transverse symmetry plane and terminal circumferential stress of the belt ply decreased，the tire strength and loading capacity were improved.With aramid fibers in the cap ply，the shoulder stress and terminal circumferential stress of cap ply decreased significantly，the uniformity of stress distribution was improved，and the probability of terminal failure of skeleton material was reduced. |
