| 中文摘要: |
| 研究边界条件、充气压力和部件质量对半钢子午线轮胎各阶径向计算模态的影响。结果表明：轮胎-轮辋摩擦因数与轮胎各阶径向模态频率呈负相关，且阶次越高，变化程度越小；充气压力每增大50 kPa，轮胎各阶径向模态频率增大3%～11%，高阶模态受充气压力影响更大；各部件中胎面质量对轮胎各阶径向模态频率影响较大，其质量减小5%，轮胎各阶径向模态频率增大约0.8%，胎体质量影响其次，胎侧质量影响较小，胎圈质量无影响。 |
| 英文摘要: |
| The effects of boundary conditions，inflation pressure and component mass on the radial computational modal of steel-belted radial tire were studied.The results showed that there was a negative correlation between the tire-rim friction coefficient and the radial modal frequencies of each order of tire，and the higher the order was，the smaller the degree of change was.When the inflation pressure increased by 50 kPa，the radial modal frequency of each order of tire increased by 3%~11%，and the higher-order modal was more affected by the inflation pressure.The tread mass of each component had a greater impact on the radial modal frequencies of each order，with its mass reduced by 5%，the radial modal frequencies of tire each order increased by about 0.8%.The carcass mass had a second impact，the sidewall mass had a smaller impact，and the bead mass had no impact. |
