| 中文摘要: |
| 对不同规格轮胎进行室内性能试验，研究胎体帘线压延密度对轮胎力学性能的影响。结果表明：增大胎体帘线压延密度，轮胎的横向刚性和纵向刚性增大，有利于提高轮胎的操控稳定性，但同时轮胎的径向刚性增大，不利于轮胎的乘坐舒适性；轮胎的接地印痕面积增大，接地印痕趋于矩形，接地压力分布更加均匀；轮胎的侧偏刚度略有提升，但变化较小；胎体帘线压延密度变化对不同规格轮胎力学性能的影响规律基本相同。 |
| 英文摘要: |
| The effect of calendering density of carcass cord on the mechanical properties of tire was studied through indoor performance tests of different specifications of tires.The results showed that，increasing the calendering density of carcass cord，the lateral stiffness and longitudinal stiffness of tire were improved，which was conducive to improve the handling stability of tire，but at the same time，the radial stiffness of tire increased，which was not conducive to the ride comfort of tire.The footprint area of tire increased，the footprint tended to be rectangular，and the grounding pressure distribution was more uniform.The cornering stiffness of tire increased slightly，but the change was small.The effect of the calendering density of carcass cord on the mechanical properties of tires with different specifications was basically same. |
