摘　　要：研究了一种轮胎固有频率和阻尼比辨识的数值-实验混合方法。数值分析采用非线性有限元方法对强非线性黏弹性轮胎进行模态分析,给出轮胎有阻尼固有频率和无阻尼固有频率的求解,利用模态分量法辨识出各阶模态下的阻尼比。仿真计算结果和实验结果的对比表明,给出的求解固有频率和阻尼比的方法是可靠的。The numerical and test method that can be used to identify the natural frequency and damping ratio of a tire was developed.Under this condition,the calculation method for natural frequency（with or without damping）and damping ratio has been developed with FEA software.The component analysis method was used to calculate the damping ratio.The comparison between the result of calculation and test showed that the calculation method is operable and reliable.
