摘要
针对半钢子午线轮胎钢丝圈采用钢丝根排和单根钢丝缠绕两种结构形式,研究半钢子午线轮胎胎圈强度的计算公式。结果表明:钢丝圈为根排结构且标准充气压力大于340kPa的半钢子午线轮胎,需修正钢丝圈安全倍数的计算公式,修正系数为0.789;钢丝圈为根排结构且标准充气压力不大于340kPa以及钢丝圈为单根钢丝缠绕结构的半钢子午线轮胎,不需要修正钢丝圈安全倍数的计算公式,利用公式可以实现半钢子午线轮胎胎圈水爆压力值的预测与计算,规避产品设计风险。
The bead strength calculation formula of steel-belted radial tire was studied based on two types of bead core construction which were rectangle wire bead and single wire bead, respectively. The results showed that ,for the steel-belted radial tire, when the bead construction was rectangle wire and at the same time the standard inflation pressure was bigger than 340 kPa, the formula needed to be corrected by a coefficient of 0. 789. Otherwise the formula was correct. When the bead construction was a single wire bead,it would not need the correction, either. The water pressure burst value could be calculated by using the formula,which could reduce the product design risk.
