摘要

选择A,B和C公司生产的不同结构225/55ZRF17缺气保用轮胎为研究对象,进行轮胎断面剖析和结构分析,并进行静负荷试验,在标准负荷下,分别测量轮胎在标准充气压力和零充气压力下的下沉量,计算两种条件下轮胎下沉量的变化。结果表明,A,B和C公司生产的225/55ZRF17缺气保用轮胎下沉量的变化量分别为23.7,11.4和9.8 mm,C公司生产的缺气保用轮胎自身负荷能力最强。
        The 225/55 ZRF17 run-flat tires with different structure were selected as the research objects,which were produced by different companies:company A,B and C.The cross-section and structure of the tires were analyzed,and the static load tests were carried out.The sinkage of tire was measured under standard inflating pressure and standard load,and then measured under zero inflating pressure and standard load.The sinkage difference of tire under these two conditions was calculated.The results showed that the sinkage difference of 225/55 ZRF17 run-flat tires produced by company A,B and C was 23.7,11.4 and 9.8 mm,respectively,and the run-flat tire produced by company C had the highest self-loading capacity.
