中文摘要：

基于自然软骨配置的不规则的表面，联合在自然软骨对之间的运动的 tribological 特征被旋转偏移量和速度的变化调查。接触排水量，接触负担，磨擦力量和从自然软骨对的磨擦的系数被一台 UMT-2 严峻的机器测量。为了获得，稳定的部分和起浪的部分，接触负担和接触排水量被五点的滑动平均方法再混合物。这些结果证明接触负担由稳定的负担和起浪的负担组成。并且接触排水量由软骨变丑和表面轮廓组成。当自然软骨变丑与滑动时间线性地非增加了时，稳定的负担类似于外面的负担。起浪的负担有 0.235 由于磨擦配置的不规则的表面与表面构画出的关联词系数。从软骨磨擦配置的磨擦的系数被更小的大小少些在旋转参数影响。一些奇怪的顶点在磨擦的系数的区域被获得，并且显著地与相应于接触负担的本地最小的价值联系了。旋转偏移量在接触排水量上在接触负担和细微影响上有清楚的影响。更大的偏移量生产了接触负担的更高起浪的大小。旋转速度在软骨变丑起了一个明显的作用，但是在接触负担上有更少影响。更低的速度带了更大的软骨变丑。

英文摘要：

Based on the irregular surface of natural cartilage configurations, the tribological characteristics of coupling motion between natural cartilage pairs were investigated by the variation of rotated offset and velocity. Contact displacement, contact load, friction force and coefficient of friction from natural cartilage pairs were measured by a UMT-2 testing machine. In order to obtain the steady part and wavy part, the contact load and contact displacement were decompounded by the five-point sliding average method. These results showed that the contact load was composed of steady load and wavy load. And the contact displacement was composed of cartilage deformation and surface outline. The steady load was similar to exterior load while natural cartilage deformation increased nonlinearly with the sliding time. Wavy load had the correlative coefficient 0.235 with surface outline due to the irregular surface of fric- tion configurations. The coefficient of friction from cartilage friction configurations was less influenced by smaller magnitude in rotated parameters. A few strange summits were obtained in the area of coef- ficient of friction, and significantly related with local minimal values corresponding to the contact loads. The rotated offsets had clear impact on contact load and a slight impact on contact displacement. Larger offset produced higher wavy magnitude of the contact load. The rotated velocities played an evident role in cartilage deformation, but had a less influence on contact load. Lower velocity brought larger cartilage deformation.
