(接上期)6.4.5用优选参数进行轮胎模型的模态分析用根据第4章进行的参数研究推导出的选定参数对非线性有限元模型进行分析以评估轮胎的振动形式和自然频率。用筛选出的选定参数研究的轮胎模型的变形形式图示于图84。比较从标定轮胎模型(图84)筛选的这些变形形式表明,变形形式1、2、3、6和9具有相似的变形图形。但是,用选定参数建立的模型的其它变形形式与从标定轮胎模型筛选的那些变形形式有很大的不
(Continued) 6.4.5 Modal Analysis of Tire Models with Preferred Parameters Nonlinear FEA models are analyzed using the selected parameters derived from the parametric studies performed in Chapter 4 to evaluate the tire’s vibrational patterns and natural frequencies. A deformed version of the tire model studied with the selected selected parameters is shown in FIG. 84. Comparing these variants screened from the calibrated tire model (FIG. 84) shows that variants 1, 2, 3, 6 and 9 have similar deformation patterns. However, other variants of the model established with the selected parameters are quite different from those variants screened from the calibrated tire model
