Effect of the expansion rate of contact patch, due to wear of material, on the frictional temperature was analyzed in pure slide of wheel on rail.

结果表明：接触斑材料的磨损速度只影响磨损过程中的温度场分布，其稳态温度场分布基本一致；热载荷随着纵向载荷、蠕滑率以及摩擦系数的增大而增大，进而影响轮轨滚动接触热疲劳。

Direct contact with the skin next to the skin clothing cotton socks and so on in order to better avoid direct contact with skin and wool.

直接接触皮肤的贴身衣物棉袜等，以便更好地避免与皮肤直接接触和羊毛。

It is shown that the contact interaction enables bottom drillstring to whirl backward, and then an alternate bending stress with higher frequency is produced. So the drillstring fatigue failure could be accelerated. At the same time, a quite strong wallop force of high frequency is produced on the contacting point, and the contacting zone is next to the screw coupling of drill collars. It will easily result in the failure of screw couplings. The research results provide theoretical basis for the prevention of drillstring failure.

研究表明，下部钻柱与井壁的碰摩作用使下部钻柱反向涡动，产生高频的交变弯曲应力，会加速下部钻柱疲劳破坏；下部钻柱与井壁接触点处存在较大的高频冲击力，并且接触区域靠近钻铤螺纹联结处，更容易诱发螺纹联结处失效，该研究成果可为预防钻柱失效提供理论依据。
