| 中文摘要: |
| 基于轮胎纵滑试验的数据辨识模型参数，建立轮胎纵滑模型，提出基于魔术公式计算轮胎纵滑特性参数的方法，可计算任意负荷下轮胎的动态纵向刚度、最大附着力因数和滑动附着力因数等参数。结果表明，基于魔术公式的轮胎纵滑特性参数计算结果与测试结果的一致性很好。本方法可为轮胎研发部门和汽车厂轮胎性能改进提供有力的数据支持。 |
| 英文摘要: |
| Based on the data of tire longitudinal slip test，the parameters of the model were identified， the tire longitudinal slip model was established，and the method of calculating the tire longitudinal slip characteristic parameters based on magic formula was proposed.The dynamic longitudinal stiffness，maximum adhesion coefficient and sliding adhesion coefficient of the tire under any load could be calculated.The results showed that the calculation results based on magic formula were in good agreement with the test results.This method could provide powerful data support for tire performance improvement of tire research and development department and automobile factory. |
