【Abstract】 The mechanism of upgrading and strengthening the materials of FZ-8 new supporting slide tracks for steel gates of hydraulic structures was analyzed and compared with the original materials of steel-base copper-plastics slide tracks from the viewpoint of structural composition and compounding technology of materials. The static bearing capacity, friction factor, wearing life and dynamic compound strength of these materials were tested by simulated experiments, the impact-resisting and scrape-resisting properties of the materials of the new slide tracks were examined. Results showed excellent comprehensive properties of these materials. This research provides technical parameter for selecting materials of supporting slide tracks for various gates of the Danjiangkou project to be hightened.更多还原
