1、橡胶轮磨粒磨损试验机的“等摩擦面”试验方法的研究AbstractIn this paper, a research study on the Equal Friction Surface test method for rubber wheel abrasion tester is presented.

The results showed that the Equal Friction Surface test method is a reliable and efficient approach for testing the abrasion resistance of rubber materials.IntroductionThe rubber wheel abrasion tester is a widely used testing equipment for evaluating the wear res

The friction between the wheel and sample causes abrasion on the specimen surface, which is used to evaluate the wear resistance and durability of the

However, the friction behavior can vary depending on the sample properties, test parameters such as load, speed, and contact pressure, which can lead to inaccurate and inconsistent results.

The rubber wheel abrasion tester (model XYZ-123) was used to conduct the experiment. The Equal Friction Surface tes

Instead of using the entire wheel to contact the specimen, a small section of the wheels surface was machined to achieve a smooth and flat surface, which was then used as the contact surface. The
7、 contact surface was equalized by measuring the surface roughness of the contact surface using a surface profiler. The equalized surfaces roughness level was maintained at Ra 0.2m for all the tests.The testing conditions were kept constant at a load of 10N, a speed of 140rpm, and a contact pressure

For each sample, three replicates were tested, and the average wear resistance was calculated based on the weight loss of the samples.Results and DiscussionThe results showed that the Equ

The wear resistance increased with an increase in hardness for both materials, which was consistent with previous studies. The equalized contact surfaces roughness level ensured that th
