摘　　要：利用Matlab中Optimization Toolbox所提供的L-M Method优化算法,结合一整套完整的乘用车轮胎试验数据,对最新半经验MF-Tyre 6.11模型进行了纯工况和联合工况的参数辨识,同时对83个参数辨识结果进行残差分析.结果表明,所采用的辨识流程和优化算法能够准确地辨识出参数,且辨识结果最大残差不超过5%,有效解决了MF-Tyre模型参数辨识不全和参数难以准确辨识的问题.The newest semi-empirical MF-Tyre 6.11 model is used for parameter identification under pure and combined slip conditions via a set of passenger car tire test data,using L-M Method of optimization algorithm provided by toolbox in Matlab.The residual analysis of 83 parameter identification results is conducted.Rsults show that this identification process and optimization algorithm are able to accurately identify the parameters and the largest residual of identification results is no more than 5%.The problems of MF-tyre model parameters which are identified incompletely and inaccurately are solved effectively.
