Simulation on tread Rubber Cutting Resistance of Aircraft tire

With the development of aerospace industry, the take-off speed, landing speed and load of aircraft suffered by the aircraft are getting larger and larger. The requirements for tire performance are also getting higher and higher, especially for large aircraft tires. Aircraft tires as the only grounding parts of aircraft, plays an important role in aircraft safety. Due to the large aircraft landing speed, aircraft tires leaving a black mark on the ground when contacting with it, which is the rubber particles caused by the severe wear between the rubber and various sharp objects under the conditions of high temperature, high pressure and high speed difference. Abrasion resistance at high speed is an important indicators of aircraft tires, which is a direct impact on the safety of the tire. Therefore, the aircraft tire tread rubber is used as the research object in this paper, the high-speed cutting is used to characterize the wear resistance of the tread rubber and different sharp objects in the high-speed landing of the aircraft tire. Based on the Mooney-Rivilin constitutive model of rubber, a high-speed cutting model of tread rubber and different sharp objects was developed by ABAQUS software. The cutting performance of different sharp objects and tread materials was systematically studied under different tool angles and speed, which can evaluate the wear resistance of tread rubber in this harsh environment. Results indicated that the cutting force, cutting temperature have great relevance to the cutting resistance of tread rubber, which can be used to characterize the wear resistance of aircraft tires under harsh environment.
