| 中文摘要: |
| 针对12R22.5全钢轮胎出现的轮胎胎圈部位内凹和胎体帘线抽出等缺陷，利用有限元分析技术对成型机扇形块轮廓形状进行优化。通过扇形块参数调整使其横向压紧力、垂向压紧力和胎圈部位面积达到优化目标，使用优化后的扇形块提高了成型胎坯工艺质量和稳定性，同时延长了成型胶囊使用寿命。 |
| 英文摘要: |
| Aiming at the defects of the 12R22.5 all-steel tires such as the concave of the tire bead and the extraction of the carcass cord，the finite element analysis technology was used to optimize the contour shape of the building machine sector block．By adjusting the parameters of the sector block，the lateral compression force，vertical compression force and the bead area could reach the optimization target.The quality and stability of the green tire were improved and the service life of the building capsule were prolonged by the optimized sector block. |
