钢丝帘线刚度的探讨

Study on stiffness of steel cord

探讨结构不同破断力相同(近)、结构和单丝直径相同而单丝强度等级不同、结构相同单丝直径不同以及同一结构有无外缠丝等因素对钢丝帘线刚度的影响。通过数据对比表明,同一结构钢丝帘线单丝直径不同及有无外缠丝对钢丝帘线刚度影响最大,为保证轮胎的生产和质量,必须有效控制外缠结构钢丝帘线的刚度。

The influences of the structure, rupture strength, filament diameter and strength, and wrap on the stiffness of steel cord were investigated. It was found through the obtained data that in case of the same structure, the filament diameter and the wrap had the most important effect on the stiffness of steel cord;and the stiffness of the steel cord with wrap must be effectively controlled to secure the normal production and good quality of tire.
