| 中文摘要: |
| 分析了轮胎模态分析的试验方法及其在轮胎设计中的应用，并建立了轮胎模态分析试验系统。测量了各类型轮胎的固有频率特性，分析了轮胎气压、胎面花纹和轮胎质量对轮胎的固有频率特性的影响规律、模态振型与振动和噪声的关系，得出结论:轮胎气压增大，轮胎的固有频率也随之增高;同型号、同规格光面轮胎的基频低于有花纹轮胎;轮胎刚度变化对轮胎固有频率的影响大于轮胎质量的影响。此外，还用试验模态验证了有限元模态分析的正确性及产生误差的原因。 |
| 英文摘要: |
| The tire modal test and its application to the tire structure design were analysed ,and a tire modal analysing test system was established.The inherent frequency characteristics of various tires was determined ,the effective law of tire inflation pressure ,tread patterns and tire weight on the inherent frequency characteristics of tires was analysed.It was found that the inherent frequency increased as the tire inflation pressure increased ;the basic frequency of the tire with tread patterns was lower than that without tread patterns in the same type and size ;the influence of the tire stiffness on the inherent frequency was greater than that of the tire weight.The FEA of tire modal was confirmed and the cause of deviation was diagnosed by the modal test. |
