| 中文摘要: |
| 分析无内胎全钢载重子午线轮胎均匀性影响因素，重点考察轮胎径向力波动（RFV）和侧向力波动（LFV）的影响因素，以及半成品部件接头定位角度分布和左右胎圈质量偏差对轮胎均匀性的影响。结果表明：轮胎RFV的主要影响因素为半成品部件接头定位角度分布、成型机精度和稳定性；轮胎LFV的主要影响因素是胎面尺寸偏差、半成品部件质量分布、成型压辊对称性和滚压参数；采取在成型鼓和辅鼓上标识各半成品部件接头位置、调整成型鼓限位行程开关、成型时对半成品胎圈进行称量并配对使用等措施，可有效提高轮胎均匀性。 |
| 英文摘要: |
| The factors which influence the uniformity of tubeless TBR tire were analyzed. Particularly，the factors influencing radial force fluctuation（RFV） and lateral force fluctuation（LFV） were analyzed. The effect of the positioning angle distribution of semi-finished parts and the weight deviation of left and right beads on tire uniformity were investigated. The results showed that the main factors influencing RFV were the positioning distribution of semi-finished parts，and the precision and stability of the forming machine. The main factors affecting the tire LFV were the tread size deviation，the mass distribution of the semi-finished parts，the symmetry of rollers and rolling process parameters. In order to improve tire uniformity，the joint positions of semi-finished parts were marked on the building drum and auxiliary drum， the drum position limit switch was also adjusted，and the semi-finished beads were weighed and used in matched pairs. |
