利用试验模态参数对轮胎包容特性的建模及试验验证 总被引:1,自引:1,他引:1
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。 相似文献

A lumped tire model was developed with consideration of the enveloping property in order to predict the natural tire frequency.
Tire stiffness was classified into vertical, sidewall, and enveloping stiffnesses, and the tire characteristics were analyzed
in detail experimentally and via finite element analysis. In addition, the effective masses of the tire tread and belt were
extracted directly from design specifications taking into account the sizes and material properties of different rubber blocks.
Using the design parameters of the tires, natural frequencies were calculated from the derived model and were compared with
experimental results. Finally, based on good agreement with experimental results, sensitivity analysis was performed to verify
the effect of tire stiffnesses on the natural frequencies. 相似文献
