| 中文摘要: |
| 研究3×0.24/9×0.225CCST钢丝帘线在全钢载重子午线轮胎胎体中的应用。结果表明：与3＋9＋15×0.175＋0.15钢丝帘线相比，3×0.24/9×0.225CCST钢丝帘线直径和线密度小，渗胶性能好，疲劳寿命长，弹性模量大，其他性能相当；以3×0.24/9×0.225CCST钢丝帘线替代3＋9＋15×0.175＋0.15钢丝帘线用于全钢载重子午线轮胎胎体，成品轮胎强度、高速性能和耐久性能相当，满足轮胎使用要求，同时可减小轮胎质量，降低生产成本。 |
| 英文摘要: |
| The application of 3×0.24/9×0.225CCST steel cord in the carcass of truck and bus radial tire was studied.The results showed that，compared with 3＋9＋15×0.175＋0.15 steel cord，3×0.24/9×0.225CCST steel cord had smaller diameter and linear density，better permeability，longer fatigue life，bigger elastic modulus，and other properties were equivalent.Using 3×0.24/9×0.225CCST steel cord to replace 3＋9＋15×0.175＋0.15 steel cord in the carcass of truck and bus radial tire，the strength，high-speed performance and durability of the finished tire were equivalent，and met the tire use requirements，while the weight of the tire and the production cost could be reduced. |
