摘 要: | 对195/60R14轮胎进行了模态试验,得到前17阶的模态参数,计算出轮胎柔度,应用指数函数拟合截取不同阶次得到的轮胎柔度,分析研究了模态截断对轮胎柔度的影响,当截取前10阶模态时,模态截断误差小于10%,截取前12阶时,误差小于5%。

The Effect of Modal Truncation on Tire Compliance |
| |
Abstract: | To study the effect of modal truncation on tire compliance,a modal testing of a 195/60R14 tire is performed and the modal parameters of first 17 modes are extracted Tire compliance is calculated by using different number of modes acquired by exponential function fitting The error is less than 10% when using first ten modes and will be less than 5% when first twelve modes are used |

Keywords: | Tire Modal test Modal parameter Tire compliance Modal truncation |
