橡胶轮磨粒磨损试验机的“等摩擦面”试验方法的研究
6页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 study aimed to investigate the effect of the test parameters on the friction behavior of the test materials, and to optimize the test method for better accuracy and repeatability. The results showed that the Equal Friction Surface test method is a reliable and efficient approach for testing the abrasion resistance of rubber materials.Introdu
2、ctionThe rubber wheel abrasion tester is a widely used testing equipment for evaluating the wear resistance of rubbers, plastics, and other materials. The machine applies a force to a rotating rubber wheel that is pressed against the test specimen. 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 material. However, the friction behavior can vary depending on the sample properties, test parameter
3、s such as load, speed, and contact pressure, which can lead to inaccurate and inconsistent results. In this study, the Equal Friction Surface test method is introduced to optimize the rubber wheel abrasion tester, aiming at improving the accuracy and repeatability of the test results.Materials and MethodsThe test materials used in this study were Neoprene rubber and Nitrile rubber. The rubber wheel abrasion tester (model XYZ-123) was used to conduct the experiment. The Equal Friction Surface tes
4、t method involved a modification of the standard test method by changing the rubber wheels contact area. 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 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.Th
