    摘要
  • 摘要: 利用自行研制的振子式摩擦儀測定了聚乙烯醇水凝膠自摩擦副、人關節軟骨/聚乙烯醇水凝膠摩擦副的摩擦因數,并根據其Stribeck曲線對其摩擦潤滑機理進行初步探討,實驗結果表明,在透明質酸潤滑條件下,聚乙烯醇水凝膠與人關節軟骨具有相似的摩擦學特性,且聚乙烯醇水凝膠自摩擦副的摩擦因數略小于聚乙烯醇水凝膠/人軟骨的摩擦因數,由其Stribeck曲線初步判定其潤滑機制為液膜潤滑。

     

    Abstract: An oscillator-type tribometer was used to determine the friction factor of lubricated sliding pairs made of poly (vinyl alcohol) hydrogel/poly (vinyl alcohol) hydrogel and human articular cartilage/poly (vinyl alcohol) hydrogel respectively, and the research of the lubricating mechanism was carried out according to Stribeck curves. The experimental results show that when the hyaluronic acid (HA) is used as an artificial synovial fluid, poly (vinyl alcohol) has similar frictional characteristics with human articular cartilage and the friction factor of poly (vinyl alcohol) hydrogel/poly (vinyl alcohol) hydrogel is smaller than that of human articular cartilage/poly (vinyl alcohol) hydrogel. It is concluded that the two lubricating mechanisms are both liquid film lubricate.
