| Abstract: |
| Considering the gas permeability difference and the transient gas diffusion process of tire structural compounds，a more accurate finite element model was established to simulate the tire inflation pressure loss process，and predict the tire inflation pressure loss rate（IPLR）.The results showed that the difference of simulation value with test value on the tire IPLR was within 10%，which illustrated the finite element model could accurately describe the tire inflation pressure loss process.This development would help improve the tire pressure retention performance and support the tire aging research. |
