| 摘 要： | 利用自行研制的振子式摩擦仪测定了聚乙烯醇水凝胶自摩擦副、人关节软骨/聚乙烯醇水凝胶摩擦副的摩擦因数,并根据其Stribeck曲线对其摩擦润滑机理进行初步探讨.实验结果表明,在透明质酸润滑条件下,聚乙烯醇水凝胶与人关节软骨具有相似的摩擦学特性,且聚乙烯醇水凝胶自摩擦副的摩擦因数略小于聚乙烯醇水凝胶/人软骨的摩擦因数,由其Stribeck曲线初步判定其润滑机制为液膜润滑.

| 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 their Stri-beck curves. The experimental results show that when the hyaluronic acid (HA) is used as an artifical 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. According their Stribeck curves it is concluded that their lubricating mechanisms are both liquid film lubricate. |
