| Abstract: |
| 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. |
