【摘要】 利用试验模态参数建立轮胎模型,计算了轮胎的静包容特性,计算结果与文献中所揭示的包容现象及变化规律有很好的定性一致。在此基础上对轮胎包容特性的建模进行了定量分析,包括模态阶数的截取和胎侧非线性的刚度。将计算结果与平板式轮胎试验台上进行的试验结果相比较,表明记入以上两方面考虑的因素下,计算结果与试验结果在各方面均很好吻合。定量分析的结果表明,不考虑胎侧非线性时,对轮胎垂直刚度的计算结果会远远高于试验结果。更多还原

【Abstract】 A tire model is set up,using experimental modal parameters,and the enveloping properties of tire are calculated,on which a quantitative analysis is conducted.The results are compared with that of testing on a plate-type tire tester,showing good agreement with the considerations on modal order and nonlinear stiffness of tire sidewall in the analysis.But the calculation results of tire vertical stiffness are much higher than that of testing when the nonlinearity of tire sidewall is neglected.更多还原
