| 采用响应面法对非充气轮胎的固有频率（零阶）进行分析。选择影响非充气轮胎的固有频率的结构和材料参数（影响因子）并确定其取值范围，从中筛选出显著性影响因子并进行响应面模型的构建及优化分析，得到各显著性影响因子对非充气轮胎的固有频率的影响。结果表明：在其他显著性影响因子不变的前提下，非充气轮胎的固有频率随轮辐厚度和聚氨酯剪切模量的增大、非对称弧高度和轮辐长度的减小而增大；考虑两显著性影响因子的交互效应时，非充气轮胎的固有频率峰值分别在轮辐厚度最大和非对称弧高度最小、轮辐厚度最大和轮辐长度最小、轮辐厚度和聚氨酯剪切模量最大、非对称弧高度和轮辐长度最小、非对称弧高度最小和聚氨酯剪切模量最大、轮辐长度最小和聚氨酯剪切模量最大时出现。 |

| The response surface method was used to analyze the natural frequency（zero-order） of the non-pneumatic tire.The structure and material parameters（influence factors） that affected the natural frequency of the non-pneumatic tire were selected and their value ranges were determined，the significant influence factors were screened out，and the construction and optimization analysis of the response surface model were carried out，so as to obtain the influence of significant influence factors on the natural frequency of the non-pneumatic tire.The results showed that the natural frequency of the non-pneumatic tire increased with the increase of the spoke thickness and the polyurethane shear modulus and the decrease of the asymmetric arc height and the spoke length，while other significant influence factors remained unchanged.When considering the interaction effect of the two significant influencing factors，the peak natural frequency of the non-pneumatic tire occured when the spoke thickness was the largest and the asymmetric arc height was the smallest，the spoke thickness was the largest and the spoke length was the smallest，the spoke thickness and the polyurethane shear modulus were the largest，the asymmetric arc height and the spoke length were the smallest，the asymmetric arc height was the smallest and the polyurethane shear modulus was the largest，the spoke length was the smallest and the polyurethane shear modulus was the largest，respectively. |
