| 使用UG三维软件对720×320航空轮胎胎坯建模，针对胎坯均匀性侧向力进行分析，得出影响胎坯侧向力不均匀性的主要因素，并在不同速度下进行胎坯运动仿真，测得胎坯侧向力波动数据，再基于中心组合设计方法，利用Design-Expert软件建立胎坯侧向力与其主要影响因素的响应面模型。拟合结果表明，在不同转速下，成型部件（带束层和胎侧）接头误差和接头定点分布偏移与胎坯侧向力波动之间的关系采用四阶响应面方程的拟合效果最佳，带束层贴合偏移量和胎侧贴合偏移量对胎坯侧向力波动影响较大。本研究可为轮胎生产过程中部件贴合测控提供可靠的数学模型。 |

| In this study，720×320 aircraft green tire was modeled by using 3D software UG，the uniformity of the lateral force was analyzed，and the main factors affecting the lateral force uniformity were obtained. The motion simulation was carried out at different speeds，and the data of the lateral force fluctuation was measured. Based on the central composite design method，the response surface model between the lateral force of the green tire and its main influencing factors was established by using the Design-Expert
software. The fitting results showed that，at different speeds, the relationship between the forming parts（belt and sidewall） joint error and lateral force fluctuation，and the relationship between the joint fixedpoint distribution deviation and lateral force fluctuation were best fitted by the fourth-order response surface equations，and the belt lamination deviation and the sidewall lamination deviation had greater impacts on the lateral force fluctuation of the green tire. This study could provide a reliable mathematical model for the measurement and control of the part lamination in the tire production process. |
