轮胎均匀性径向特性参数影响因素的分析

摘要

通过设计均匀性试验,定性分析轮胎负荷及充气压力变化对径向特性参数的影响规律,并做出相应的回归分析曲线,用来指导均匀性测试条件设定及均匀性参数预测.研究结果发现,径向力波动及其一次谐波不随负荷变化而变化,但充气压力对其有指数影响规律.%A qualitative analysis on the factors affecting the radial parameters was carried out by changing tire load and inflation pressure based on design of uniformity experiment. The diagonal regressions curves were obtained,which were used to guide the selection of testing condition, and forecast the uniformity parameters in different conditions. The results showed that radial force variation and its lst order harmomc wave didn’t change with load,but had exponential relation with inflation pressure.
