| Abstract: |
| 46/17R20 aircraft tire and a new high performance tire called new concept double-rim aircraft tire were studied with ABAQUS software to analyze the radial and longitudinal stiffness under static load conditions and the force and grounding performance of tread during the braking process at 288 km·h-1 initial horizontal velocity were analyzed.The results showed that，compared with the traditional aircraft tire，the radial stiffness of double-rim aircraft tire under static load condition was much higher，and longitudinal stiffness was slightly lower，and during breaking，the equivalent stress of the double-rim tire was lower，and the longitudinal and lateral contact pressure distributions of tread were better.The carrying capacity，grounding performance and braking performance of double-rim aircraft tire were better than those of traditional aircraft tire and C double-rim aircraft tire with a suitable axial length of outer rim showed the best performance. |
