Problems solved by technology

The test content of this device is relatively simple, and it cannot realize friction research under complex working conditions. At the same time, the measured data needs to be deduced by formulas, and the accuracy and quality are not close enough.
The patent with application number CN201410325066.8 discloses a road surface acceleration loading wear device, which is characterized in that it can be used to simulate and study the wear between the tire and the road surface, but the patent simulates the rolling operation of the tire on the test road surface. The method of continuously spraying emery on the surface to accelerate wear, but this method is quite different from the actual working conditions, and cannot accurately simulate and test the friction and wear performance of tread rubber under various complex working conditions
At present, there is no friction and wear test device and method that can better simulate the actual working conditions for the special friction and wear forms of tank tire tread rubber and ordinary vehicle tire tread rubber. The friction and wear behavior of tread rubber under complex working conditions such as variable loads, variable speeds, and variable friction pairs poses a huge challenge

technical field [0001] The invention belongs to the field of tread rubber and road surface friction detection, and in particular relates to a tread rubber friction and wear test device and method for simulating the service working conditions of tank road wheels. Background technique [0002] The friction and wear of the tread rubber of the tank's heavy-duty tire directly affects the combat capability. At the same time, the performance of the tread rubber directly affects the driving safety as the area where the tire is in direct contact with the road surface. Today, the rapid development of the transportation industry has led to the improvement of the performance of tire tread rubber. Behaviors such as destruction and fatigue failure still inhibit its long-life and high-efficiency use. For this, it is necessary to provide a large number of effective experimental test data for theoretical analysis and optimization of tread rubber materials, especially for friction and wear te...
