| A global finite element model of radial tire with complex pattern was established using Abaqus software,and a fine grid finite element submodel of the belt was established based on sub-model technology.Analysis and comparison results showed that, submodel could describe the force characteristics of the belt more accurately.Under inflated condition, the stress of crown central belt was much larger than that around edges,and the force distribution on the reinforcing materials was symmetrical.Under static load condition,the crown cord force in contact area was reduced compared with inflated condition,the sidewall cord force was increased,and the cord force distribution was ra-ther asymmetrical. |
