| Abstract: |
| Considering the geometric，material and contact nonlinearities of tires，an axisymmetric model and a three-dimensional model for 11.00R20 truck radial tire were constructed by using the nonlinear finite element analysis software ABAQUS.The average wear rate of tread was obtained under standard condition.Moreover，the effects of inflation pressure，load and speed on tread wear were discussed.The results showed that，the average tread wear was 1.08 mm per 10 000 km（i.e.unit abrasion）under standard condition.Higher or lower ratio of actual pressure to standard pressure resulted in the increase of tire wear.When the load was lower than the standard load，it would cause slightly severe wear at the center of crown.On the contrary，the unit abrasion at the shoulder would increase obviously.In addition，with the increase of speed，the unit abrasion of tread increases linearly. |
