Abstract
The hypothesis of this study is that the time constant for the transient increase in friction coefficient of articular cartilage under a constant load is proportional to the size of the contact area, as predicated by the dependence of the frictional response on interstitial fluid pressurization. This hypothesis is verified experimentally from measurements of the frictional response of bovine articular cartilage disks of three different diameters (4, 6 and 8mm) against glass. At two different applied stresses (0.127 and 0.254 MPa), the coefficient of determination of a linear regression of the time constant versus the contact area yielded R(2) = 0.892 and R(2) = 0.979 (p < 0.001). The results of this study provide a cogent explanation for the expectation that the friction coefficient in situ will not achieve the elevated equilibrium values observed under common testing conditions.
摘要
本研究的假设是，在恒定载荷下关节软骨摩擦系数瞬态增加的时间常数与接触面积的大小成正比，这是根据摩擦响应与组织间液加压的相关性预测得出的。通过测量三种不同直径（4毫米、6毫米和8毫米）的牛关节软骨盘与玻璃之间的摩擦响应，对这一假设进行了实验验证。在两种不同的施加应力（0.127和0.254兆帕）下，时间常数与接触面积的线性回归决定系数分别为R(2)=0.892和R(2)=0.979（p<0.001）。本研究结果为原位摩擦系数不会达到在常见测试条件下观察到的升高的平衡值这一预期提供了有说服力的解释。
