Analysis of distribution and influencing factors of steady temperature filed of tire based on tests

摘要:

采用转鼓试验和红外热像仪对不同工况下的轮胎表面稳态温度进行了测试，探讨了升温、冷却过程中轮胎表面稳态温度场的分布规律及相应机理，并通过设计正交试验分析了负荷、胎压及车速对轮胎稳态温度的影响，确定了影响轮胎表面温度的主次因素。结果表明：负荷对轮胎表面温升的影响最大；升温过程中胎肩处的表面温度最高；冷却过程中轮胎表面出现了急剧的升温过程。

Abstract:

To explore temperature field distribution and the corresponding mechanism in heating process and cooling process, the steady surface temperature of rolling tire is experimentally measured by a rotating drum test and infrared thermal imager under different conditions. The effects of speed, load and tire pressure on tire steady surface temperature are analyzed through orthogonal experiment, and the main and secondary factors effecting tire steady surface temperature are determined. The results show that: load is the maximum factor on temperature rise; the highest surface temperature is located at tire shoulder in heating process; there is a dramatic heating process in tire surface in cooling process.
