轮胎垂直方向刚性环模型

Tire Vertical Rigid-ring Model

为研究轮胎在中等频率时的垂向力学特性,建立了垂直方向上的刚性环模型,对1/4车模型进行了振型分析,说明刚性环模型能反映中频时的振动。简单介绍了模型输入和轮胎动态特性试验,并将模型和试验结果进行了对比,表明垂直方向刚性环模型能较好反映轮胎在典型短波长不平路面上垂直方向上的力学特性。

To study the vertical force property of tire in intermediate frequency range, the vertical rigid-ring model was built. The quarter-vehicle was analyzed to show that the model was adapted to intermediate frequency. The input of the model was introduced simply, as well as the test process. The model was compared with the test data. The results showed that the vertical rigid-ring model Can accurately describe the vertical force of tire on typical short wavelength uneven road.
