| 中文摘要: |
| 采用数值仿真和正交试验方法，研究1#带束层角度、2#带束层角度、胎圈平宽、充气压力、胎面压辊压力5个成型工艺参数（简称工艺参数）对轿车子午线轮胎带束层帘线力的影响规律。结果表明，对于1#带束层帘线力而言，2#带束层角度和充气压力具有显著的正效应；对1#带束层帘线角度变化量而言，胎圈平宽（负效应）和充气压力（正效应）有相对显著的影响，但二者影响趋势相反。对于2#带束层帘线力而言，1#和2#带束层角度对其影响较为显著，二者均呈现负效应；对2#带束层帘线角度变化量而言，胎圈平宽和充气压力有相对显著的影响，二者均呈现正效应。1#和2#带束层角度及胎圈平宽对带束层力学状态有较强的交互作用影响；2层带束层角度差异较大会导致其对应的帘线力也存在较大差异，适当同步增大带束层角度，有利于降低帘线力，但会增大帘线角度的变化量。本研究可为轮胎工艺参数优化及产品质量提升提供参考。 |
| 英文摘要: |
| Numerical simulation and orthogonal test were used to study the influence of 1# belt angle，2# belt angle，flat bead width，inflation pressure and tread roller pressure five building process parameters（process parameters for short） on the belt cord force of passenger car radial tire.The results showed that，for 1# belt cord force，the 2# belt angle and inflation pressure had a significant positive effect. For 1# belt cord angle change，the flat bead width（negative effect） and inflation pressure（positive effect） had relatively significant effects，but the influence trend of the two parameters was opposite.For 2# belt cord force，1# and 2# belt angles had a significant effect on it，and both of them were negative effect.For 2# belt cord angle change，the flat bead width and inflation pressure had a relatively significant effect，and both of them showed positive effects.1# and 2# belt angles，and flat bead width had strong interaction effects on the mechanical state of the belt.The large angle difference between the two belts would lead to a large difference of the corresponding cord force.Appropriately increasing the belt angle synchronously would help reduce the cord force，but would increase the cord angle change.This study could provide reference for the optimization of tire process parameters and the improvement of product quality. |
