| 中文摘要: |
| 采用TECO理论对子午线轮胎胎坯一次定型生产工艺进行研究，借鉴无带束轮胎箍紧系数的概念，得到胎坯充气定型时胎踵宽度的计算原理，并提出相应的数值计算方法。对收敛域进行分析，并研究帘线长度函数，得到单调递增区间（a/m处于0.621.8），在此区间内使用两分法收敛效果较好。 |
| 英文摘要: |
| The principle of computing inflated building bead heel width for radial tire and its relevant algorithmic method were given by study on one-step building by TECO and the coefficient of tight binding of non-belted tire.The convergence domain and length function of ply were analyzed to give the monotone increasing interval（a/m=0.62～1.8），in which the effect of convergence was better by using dichotomy. |
