| 中文摘要: |
| 对12R22.5无内胎和12.00R20有内胎全钢子午线轮胎进行有限元仿真分析，分别对有、无胎面两种模型的轮胎胎圈部位进行受力分析，对比胎体反包端点应变能密度。结果表明：磨掉胎面轮胎的胎圈部位受力情况与正常轮胎相当，因此磨掉胎面再进行胎圈耐久性能试验能够更有效地反映正常轮胎的胎圈受力情况。 |
| 英文摘要: |
| Finite element analysis of 12R22.5 tubeless and 12.00R20 with tube all-steel radial tires was carried out.The force analysis of the bead with and without tread models was carried out respectively，and the strain energy density at the end point of the carcass backpacking was compared.The results showed that the force on the bead of the worn tire was similar to that of the normal tire，so the bead durability test by the worn tire could reflect the force on the bead of the normal tire more effectively. |
