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

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.
