Three-body wear is the primary mechanism in friction pair between groove side and scraper. This study quantitatively investigates effect of textures on three-body under different factor combinations through abrasive experiments. The results indicate that significantly reduce samples. reduction rate sample reaches 41% optimal combination. Width, depth, tilt angle influence loss. Among these factors, width exhibits a negative change loss, while depth show positive effects. Additionally, there are interactive effects loss as well angle. process to was qualitatively analyzed by discrete element method (DEM) simulation. Combined with morphologies, wear-resistant explored. can mitigate severity wear, contact area particles samples, alter movement enhance resistance. Meanwhile, serve guiding modify direction transform sliding motion coal into rolling motion, converting continuous “face-face” intermittent “point-face” “line-face” contacts. provides novel ideas theoretical foundations for designs mining machinery equipment.
