| 中文摘要: |
| 将充气压力分为3个区间，计算12R22.5 152/149L无内胎子午线轮胎在标准下沉量（33.7 mm）下负荷与充气压力的函数关系。结果表明：当充气压力为200～300 kPa时，轮胎负荷与充气压力的函数关系采用傅里叶函数表征；当充气压力为300～800 kPa时，采用线性函数表征；当充气压力为800～950 kPa时，采用傅里叶函数表征。 |
| 英文摘要: |
| Dividing the inflation pressure into three sections，the function relation between load and inflation pressure of 12R22.5 152/149L tubeless radial tire under standard deflection（33.7 mm） were calculated.The results showed that the function relation between load and inflation pressure of tire should be characterized by Fourier function under 200～300 kPa inflation pressure，while it should be characterized by linear function under 300～800 kPa inflation pressure and it should be characterized by Fourier function under 800～950 kPa inflation pressure. |
