| 中文摘要: |
| 讨论了轮胎的静负荷性能，用试验数据分析了轮胎的气压与负荷对其下沉率、接地面积、硬度因数、接地因数以及接地压力分布的影响，采用回归方程分析了轮胎的气压2负荷2下沉率三者之间的关系。试验结果表明，轮胎承载能力主要受下沉率的制约，同时也受硬度因数、接地因数等性能的影响，只有做到气压-负荷-下沉率之间的合理匹配，才能保证轮胎的使用性能和寿命。 |
| 英文摘要: |
| The static load capacity of tire was discussed，the influence of tire inflation pressure and load on its deflection，ground-contact area，ground-contact factor and ground pressure distribution was analysed from the test data，and the relationship among tire inflation pressure，load and deflection was analysed by using the regression equation. The results showed that the load capacity of tire was mainly rest rained by the deflection，and also affected by the hardness factor and ground-contact factor；and the optimum performance and tread life could be obtained only when the inflation pressure，load and deflection were reasonably matched. |
