Abstract Part I describes the tire structure model; part II the contact detection and contact interface models for rigid and deformable terrains; part III the model parameterization and validation. Model parameters are estimated using non-linear least-square optimization to minimize the error between the Hybrid Soft Soil Tire Model (HSSTM) predictions and experimental data. The parameterization routines’ initial conditions are estimated from modal analysis in radial and circumferential directions. The preliminary parameterized model is incorporated in the optimization routine to find tire sidewall and belt parameters in the radial direction using quasi-static cleat loading test data. The vertical force at the spindle and tire contact patch are used to study the model accuracy in the radial direction. FlatTrac tire longitudinal and lateral force test data are employed to estimate the parameters in these directions. The tire shear force and moment at the spindle are validated against experimental data for lateral dynamics performance.

混合软土轮胎模型 (HSSTM)。第三部分：模型参数化和验证

摘要 第一部分描述了轮胎结构模型；第二部分刚性和变形地形的接触检测和接触界面模型；第三部分模型参数化和验证。使用非线性最小二乘优化来估计模型参数，以最小化混合软土轮胎模型 (HSSTM) 预测与实验数据之间的误差。参数化程序的初始条件是从径向和圆周方向的模态分析中估计出来的。初步参数化模型被纳入优化程序，以使用准静态夹板加载测试数据在径向方向上找到轮胎侧壁和带束层参数。主轴和轮胎接触面处的垂直力用于研究径向方向的模型精度。FlatTrac 轮胎纵向和横向力测试数据用于估计这些方向的参数。轮胎剪切力和主轴上的力矩根据横向动力学性能的实验数据进行了验证。
