轮胎非稳态侧偏理论模型的参数辨识

PARAMETER IDENTIFICATION OF THE NONSTEADYSTATE TIRE CORNERING THEORETICAL MODEL

根据空间域内轮胎非稳态侧偏试验数据计算出试验频率特性，由考虑胎体复杂变形的轮胎非稳态侧偏理论模型与试验数据建立了参数辨识数学模型，并辨识出模型的结构参数。理论结果与试验数据的一致，验证了模型的正确性。辨识出的参数还可以用于轮胎力学和汽车动力学的分析与仿真计算。

オhe test frequency response is calculated based on test data of nonsteady state tire cornering properties in spatial domain. The mathematical model for structure parameter identification is established according to test data and the theoretical model of nonsteady state tire cornering properties taking the complex deformation of carcass into account. Then the structure parameters are identified and the tire theoretical model is validated from the agreement between test data and calculated results. The identified structure parameters can also be applied to analysis and simulation studies of tire mechanics and automobile dynamics.
