摘要

PPROBLEM TO BE SOLVED: To provide a method for accurately simulating the rolling resistance of a tire, and further to provide a model for numerical analysis to be suitably used in this simulation, and to provide a method for forming the model. PSOLUTION: The analysis of the rolling state of the tire on a road surface at a constant speed has been carried out by modeling the road surface as a drum, and by modeling the rubber members of the tire as elastic bodies. The amplitudes and frequencies of the strain in the rubber members have been derived from the wave shapes of the respective rubber elements of the tire, the wave shapes having been obtained by the analysis. After that, the viscoelastic test for a rubber material has been carried out with the obtained amplitudes and frequencies of the strain, and the viscoelastic modulus of the rubber material has been calculated. A tire model has been formed using the calculated viscoelastic modulus, and a model 10 for the numerical analysis of a tire-wheel assembly body has been formed using this tire model. The value of the rolling resistance has been obtained by carrying out the analysis of the rolling. PCOPYRIGHT: (C)2007,JPO&INPIT

解决方案：通过将路面建模为鼓形，并通过将轮胎的橡胶构件建模为弹性体，来进行轮胎在恒定速度下在路面上的滚动状态的分析。橡胶构件中的应变的振幅和频率已经从轮胎的各个橡胶元件的波形导出，该波形已经通过分析获得。之后，利用获得的应变的振幅和频率对橡胶材料进行粘弹性试验，并计算出橡胶材料的粘弹性模量。使用计算出的粘弹性模量来形成轮胎模型，并且使用该轮胎模型来形成用于轮胎-车轮组装体的数值分析的模型10。滚动阻力的值是通过进行滚动分析而获得的。
