| 中文摘要: |
| 对航空轮胎提出A（普通结构钢丝胎圈芯），B（普通结构碳纤维胎圈芯）和C（水滴型结构碳纤维胎圈芯）3种不同的胎圈芯，并采用Abaqus有限元分析软件对航空轮胎的落地瞬间进行仿真研究。结果表明，与A型轮胎相比，C型轮胎的最大接触应力降低50%以上，最大等效应力减小2/3左右，但3种不同类型轮胎接地中心点在最后时间步的接触压力与轮胎下沉量基本保持一致。 |
| 英文摘要: |
| Three different kinds of bead core for aircraft tire were presented，including the type A with the general structure and steel cord，the type B with the general structure and carbon fiber cord，and the type C with water drop structure and carbon fiber cord.The effect of the type of bead core on the tire performance during aircraft landing was investigated by finite element analysis and using Abaqus software.The results indicated that，compared with the tire having type A bead core，the maximum contact area pressure of the tire with type C bead core decreased by more than 50%，and the maximum equivalent stress was reduced by approximately two thirds.The contact area pressure and tire deformation at the landing center of the tires with different types of bead core were almost the same at the last step. |
