缺气保用轮胎在零充气压力下的负荷能力

Load Capacity of Run-Flat Tires under Zero Inflating Pressure

根据静负荷性能试验数据,利用软件对缺气保用轮胎在不同充气压力和负荷时的下沉量进行插值计算,得到标准下沉量时充气压力与负荷的关系,计算出缺气保用轮胎在零充气压力下的负荷能力。通过试验和计算得到:A公司225/55ZRF17 97W标准型缺气保用轮胎在零充气压力时的负荷能力约为193 kg,B公司225/55ZRF17 101W增强型缺气保用轮胎在零充气压力时的负荷能力约为349 kg。

According to the static load performance test data,the sinkage of run-flat tires under different inflating pressure and load was interpolated by software,the relationship between inflating pressure and load under the standard sinkage was obtained,and the load capacity of run-flat tires under zero inflating pressure was calculated.The results of experiment and calculation showed that,the load capacity of 225/55 ZRF1797 W standard tire of A company was about 193 kg at zero inflation pressure,while that of 225/55 ZRF17101 W reinforced tire of B company was about 349 kg at zero inflation pressure.
