Thermo-mechanical behavior of solid rubber tire under high-speed free rolling conditions.

Severe heat generated by the hysteresis loss can be accumulated inside of the aircraft tire during the free rolling stage, which affects the performance and safety of aircraft. In this paper, verifying a thermomechanical coupling simulation method through experiments to predict the temperature field evolution and internal temperature distribution of natural rubber during high-speed rolling. The high-speed rolling performance of the aircraft tire can be reflected by the disc-shaped specimen based on the similar working and contact conditions, which provides theoretical basis for the further application in aircraft tire. The cyclic tensile test is conducted on dumbbell rubber specimen, and the results show that the temperature increases with the strain. The simulated temperature field distribution corresponds well with the test results, and the maximum error of the temperature rise data is within 4%. Rolling test is conducted on solid rubber wheels, the error between the simulated temperature rise curve and the test is within 1.2%, which proves that this method accurately predicts the temperature evolution process of the disc rubber wheel, and provides a basis for the study of aircraft tire heat generation under different conditions.
