Abstract:
The
mechanisms of tire temperature rise are expounded firstly, namely, the
relationships of tire stress-strain and its temperature. Then, on basis
of the experimental data, the steady state thermal status of a tire
based on rolling is analyzed. The experimental data are regressed on
rolling is analyzed. The experimental data are regressed by means of
regression technique. The formula of single factor is built between tire
surface temperature rise and operating conditions, including speed,
load, inflation pressure and ambient temperature distributions in steady
state are analyzed. The formula of multi-factor is built between tire
surface temperature and operation condition also, the gained regression
equation was high reliable by means of the F testing. The regression
equation can be applied to initially predict tire temperature rise and
instruct tire design, with which supplies the foundation to study tire
blow out mechanism and put forward prevetive measures at the same time.
