| 中文摘要: |
| 为分析轮胎动态特性建立了更为复杂、细致的轮胎三维有限元模型，考虑了轮胎材料的复杂性对轮胎进行模态分析，并给出固有频率及相应振型。试验结果与计算结果有良好的一致性。还研究了充气压力对固有频率的影响，得出了允许压力范围内压力增大、固有频率随之增大的结论。 |
| 英文摘要: |
| A more complex tridimensional FE model of tire was established to analyse the dynamic properties of tire. Taking the complexity of tire materials into account,the modal analysis of tire was made with the model,and the inherent frequencies and their corresponding vibration types were given.The calculated results were well fitted to the test results.The effect of the inflationpressure on the inherent frequency was also investigated. It was concluded from the test that the inherent frequency raised as the inflation pressure increased up to the permitted value. |
