| 中文摘要: |
| 以46/17R20航空子午线轮胎和一种新型高性能新概念轮胎——双刚圈航空轮胎为研究对象，利用ABAQUS软件分析静载荷工况下的径向和纵向刚度以及以288 km·h-1初始水平速度的制动过程中胎面受力及接地性能。结果表明：与传统航空轮胎相比，静载荷工况下双刚圈航空轮胎的径向刚度显著提高，纵向刚度略有下降；制动工况下双刚圈航空轮胎胎面等效应力以及径向和纵向接触压力分布规律均明显较优。双刚圈航空轮胎的承载能力、接地性能和制动性能均优于传统航空轮胎，其中外刚圈轴向长度适中的双刚圈航空轮胎的综合性能最优。 |

| 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. |
