Problems solved by technology

[0003] For indoor testing of finished tires, traditional drum tire testing machines, flat tire testing machines and flat belt tire testing machines are generally used; however, roads paved with cement or asphalt are used for the experimental simulation of the above tire wear testing machines. , it is impossible to simulate the tire wear test under the actual uneven road conditions, that is, it is impossible to test the tire wear on the actual road indoors
[0004] For the road test of finished tires, a special inspection agency or enterprise chooses the experimental point to carry out the road test and track the mileage test data. However, for the tire wear measurement in the road test, the visual method is generally used to characterize the tire wear , human factors are large, and the accuracy of the test indicators cannot be guaranteed
[0005] At present, there is no indoor tire wear detection equipment used to simulate the tire wear experiment on the actual uneven road conditions, and there is no perfect and accurate index to represent the wear data.

Abstract

The invention discloses a tire wear prediction method, which relates to the technical field of tire wear test. In the technical field of tire wear test, the wear test is carried out according to the following steps: S1: tire sample preparation; S2: tire sample vulcanization; S3: tire sample wear test; S4: tire sample cutting; S5: tire sample swelling Treatment; S6: Tire Sample Peeling Experiment; S7: Wear Data Characterization. The road condition simulation loading device designed by the present invention can simulate the running of the tire under the real road surface to carry out the tire wear experiment, and the prediction result is closer to the tire wear degree under the real road condition; the present invention finally adopts the peel force / peel strength to characterize the wear degree , Compared with the visual inspection method under the traditional road test, the data stability is better and more objective.

Description

technical field [0001] The invention relates to the technical field of tire wear test, in particular to a tire wear prediction method. Background technique [0002] With the increase of global vehicles and the growth of types, the types of rubber tires are increasing, and the requirements for use are becoming more and more demanding. As we all know, the wear resistance of tires is an important factor in determining tire durability. [0003] For the indoor test of tire tires, traditional drum tire testing machines, flat tire testing machines and flat belt tire testing machines are generally used; however, the roads for the experimental simulation of the above tire wear testing machines are all roads paved with cement or asphalt. , it is impossible to simulate the tire wear experiment on the actual road surface with uneven road conditions, that is, the tire wear test on the actual road surface cannot be carried out indoors. [0004] As for the road test of finished tires, sp...
