| 摘 要： | 通过胎侧的薄膜模型和曲梁弯曲模型的力学分析，分别推导出了径向刚度和侧向刚度的计算公式，验证了胎侧具有随变形而减弱的非线性刚度特性，说明在直接模态参数的建模中，应考虑胎侧非线性弹性特性，为轮胎模态参数的修正提供理论基础。计算结果表明考虑胎侧非线性刚度能有效提高轮胎模态模型的精度。

| Abstract: | The formulae were deduced using tire sidewall in-extensible membrane model and curve beam model. The results using these formulae prove the tire sidewall nonlinear stiffness weakening with the deformation. Comparison between the calculated results and those of experiments validates that the precision in calculation of tire modal model can be improved by considering the nonlinear sidewall stiffness. |
